^Answers in bold^

Arga your mostly right, what i was saying is there is some cases where fitting other faction weapons is a viable option. I tough you had more the "sandbox" spirit of being able to do whatever you like, not being restricted in "cookie cutter" builds or fits that makes games less interesting imo. Im not talking of obviously gimping your bot, just give some efficiency for more versatility.

If we talk about diversity, we have turret mechs more restrictive than the missile robots.
Main combat unit in the game should be combat mech. Let's look at this:
Tyranos - can use the full profile equipment. As a bonus it has two additional slots for turrets and engineering equipment. They can neut, drain, recharge accumulators, use RSA etc.
By comparison, Kains with their missile slots are sucks. Artemis even more so.

I think you have the wrong beginning. We still have not heard the concept of developers.

What should be the game?

At the moment obvious to me that the main force in the game should be T3 combat mech. But T3 useless. In turret mechs is useless slots. Config fully equipped mechs much inferior in speed, but almost no benefit in other parameters (armor, firepower, etc.)
Absolute no concept of "Full equipped bot" and "Full t4 mk2 bot" (because problems with CPU/Reactor).

taking ewat bots you actualy proved the disparity.... have a look at troiar/ictus ... they can only fit missiles in the damage slots if they max ewar. talk about flexibility.

my plan is to train all races up to assaults to max levels reasonable just for the flexibility it allows. starting with green is the wrong thing in my case. luckily I did a mistake at the begining and thought there would be firearm bonused bots, so I clicked on turret skill mostly from the 20k starter EP.

I'm not mistaken. Turret robots should be allowed to increase non-profile missile slots with non-profile pelistal robot control. It fits perfectly into the concept of nonlinearity.

then I got that one wrong. thanks for information.

@ All of you people / trolls that are not talking about the main topic of the imbalance in the EP required to be proficient in specific DPS trees feel free to start other threads.

This topic is about how much EP it takes to train different DPS types. NOT about slot / fitting options  on bots that's another topic.

Problem: all turret skills are lumped in to a few skills making it super easy to cross train from Lasers To Magnetic Weapons to Firearms

This is not balanced to launchers as the launcher tree has no skills that transfer over to anything, where I could train sharp shooting ,  precision firing,  general firing, rapid firing, and the list goes on to have it apply to 3 different types of weapons.

Again its a real problem.  With my vagabond i was able to easily cross train weapons by only putting points into the weapon extension. All the other extensions from turrets that i had pushed up were still 100% useful.  Why cant i do this with an ictus? Give a good reason and the problem is closed i guess.

And the ones saying you shouldnt put weapons on EW mechs.... please those peoples so narrowminded stay away from this discussion.

I dont understand your question, but im sure the answer you gave is not backed up with actual knowledge. EA account are 500k more EP now. Give room to max some *** no? Atm ive adv rob, pelistal bot to 10, missile dmg to 9 and all related missile ext to 5 min. Add all the mandatory ext like fitting, accu stability, all the targeting extension to 10 etc...  I miss 100k EP from a 2nd reset that i will soon(tm) get back. All in all i didnt do the math but i was expecting it could be maxxed yes.

If by "training of turret heavy mech" you ment training BOTH nuimqol and thelodica to 10, and all the related turrets extension to 10, yes in that case 500K EP is not enough i guess. But what does this have to do with our discussion?

You all consider weapon = heavy mechs = max dps = lv 10 extension.  That has nothing to do with cross training.
Not 100% of bots that have turrets/missiles slots have faction weapon robot bonus. Got it?

So like OP said, YES, cross training between turrets is viable while between missiles/turrets is not. I DID it.  I had lv 9 nuimqol, i used mesmer to farm (yeah with EM obviously). But what i liked was vagabond MK2(and i had all jamming maxxed), so i used it often too. With my turrets extensions i had pushed to better farm with mesmer, i just did pushed laser AND firearms to an acceptable level (7 and 8 if i remember correctly) Sure its not 10, but guys 9% and 6% less dmgs is NOT a gamebreaker imo. Peoples that say otherwise...well... nm.  And i did all this with a somewhat LOW EP investment.
I never added one single level in other faction extensions.

So, cross training weapons = noob??  Believe what you want but the OP balance reclamation is valid imo.

It seems you cannot dissociate a faction extension from its weapon extension. I can have zero in thelodica faction extension and 10 in lasers, in SOME situations it can be viable. So i can have my 50% ECM power and stuff AND use lasers instead of EM on a vagabond if chose to.

I cant believe majority of the peoples debating here dont agree with the fact that this module system is ment to test and find and use fittings for particular purposes, without being locked in a way of thinking  where HM= full dps and Ewar = full ECM/Supp/Demob.

Lets look at this:

Vagabond MK2:

1 sensor amp, 2 suppressors, 1 Ldemob, 1 ecm and 1 range amp

3 lasers

1 LWF, small repper and the 2 other leg slot for cap stability.

Obviously there will be fitting req problems, especially with the lasers using max reactor. I didnt test this but i guess its somehow fesible.

Back this up with maxxed extensions.  Now you got something dangerous no?  You can keep your range with demob (demob is not only for REDUCING distance between you and your foe), suppress and ecm to keep not being hit and slowly(yeah not much DPS but when ennemy cannot do anything, except against a tank, its only a matter of minutes) kill the ennemy.

  Yeah i know PVP is NOT 1v1 etc etc..  But 10 of this and you got a real serious threat for any group of same size and EP (sure there are counter like every strategy(the reason why i love this game at first)).  See the "viability" of weapons on Ewars? Its like small ewars, they got always weapons on them, nobody says:  "Ahaha u nub Ewar dont got racial bonus on weapons u fitting weaps on ur ewar u noob!"

Id like to say im not a veteran of roaming, i did some, mostly mass pvp where all is different.  But i did survived and won 1vs4 battles while i was pve fitted and was catched "pants down" like some like to say.

So please dont hit to hard on the noob.

To keep it clear about this topic, when did the debate moved from "yes or no balance needed" to "how to give balance".

I mean peoples should be clear about their opinion.  Arga i assume you admit theres a balance issue if you try to find solutions for it?

What would close this debate is if someone of  the deciding side (read DEVS) could explain us why turrets and missiles related extensions have been separated. And if there is a reason; how it is balanced (in my case for example).  Or just say its not balanced this way but in another way. In that case just explain.  I love greens more than blue tbh. Better for a solo pveer like me. BUT one need some logic behind arbitrary decisions.

FACTS:

3 factions, 4 weapon types, most of weapons related extensions applies to 3 of the 4 weapons type, and the last one is left alone.

QUESTION:

Is it balanced?  Will we green have access to more versatility and weapon options?

Tbh i have the same opinion. I dont like the idea of restricting (less freedom = not good for sandbox) and free for all weapon would also lower the tactical aspect of the game (and reduce the impact of faction choice, wich is bad too i guess).

The third solution has already been brough up.  Waiting for a new weapon type, that would benefit from missile extensions.  If that happens someday, i hope other factions wont whine like mad dogs.

One little thing we could remember too.  Its not like WoW where there are defined sides. I tough this when i wrote "other factions".  In fact they dont exist. There are only different factions technologies. Meaning any player, corp or alliance has access to any type of technology. So the "balance" issue is lesser by this fact.
