The idea is to remove bonuses at all.
5% per level bonus can be replaced with rebalancing of extensions and extra slot.
I think, if you want to make robot bonus for you: assemble it by yourself.

I think, robot part should be like a framework with restriction.
I think, robot functionality should be assembled by combining modules and extensions.
I think, bonuses are redundant and just adding useless complexity to the game.

I think building your own robots out of pieces, rebalancing extensions, and limiting modules that robots can fit increases complexity and removes overall freedom.

It will further put focus on needing a specific robot for a specific task. It will mean that you need to remember a lot more fittings as you need to remember not only good combinations of robot parts but also the modules to use with them. While this increases freedom it also increases complexity.

If you then rebalance all extensions (Correctly) it will be a lot of work for the devs which isn't simple.

If you also restrict modules that can be placed in head and legs slots as well you're taking away freedom of choice. It's more shifting optional bonuses into set fittings. Knowing the enemy fit will be as much just looking at the hybrid robot parts.

I agree more freedom and removing complexity is needed but I do not agree with limiting robot fittings. Bonuses guide people to use a specific fit but does not require it. More mixed bonuses would be nice and more robots choice would also be nice. At the moment there are not enough visual difference when fitting robots. Rather than release more robots I think changing their looks based on player choices or fittings would be much better. Let people fit what they like and base everything on extensions and allow for customised robot looks the more extensions level you have in robot control.

Either way if Hybrids come I'd still prefer them to keep bonuses per robot part for now. I don't see this system being a big enough change to need adding. But it's a good idea to work on. If Perpetuum was in Beta I'd say it would be worth developing but now I am not so sure..

I have hugely mixed opinions on this. This is not meant to be a negative post or a positive one. Sorry if it sounds like either.

I agree, that this is a purpose of bonuses. That is why i request to remove them, because their functionality can be replaced by existing content: extensions and modules.

PP is very hardcore game. Here is no place for guidance like bonuses. I think, its hard to disagree.

Not Alex, i dont propose hard restrictions. I propose to have variety of slots for parts for each race, but their overall capabilities will reflect specific of race. For example, i want that nuimquol parts will have more repair slots that other races have, thelodica parts will have more armor resistance slots that other races have, pelistian parts will have more engeneering slots that other races have but all races will have parts with slots for race and non-race modules.
The specific is: racial parts have more racial slots than non-racial. I think this sounds reasonable.
Lets move further:
If player want to boost his own part, he will train certain extension what will improve certain fitted part. f.e. engeneering extensions for pelistian and so on.

^^ Part bonuses can be easily removed, because they are not reasonable for this simple and clear picture.

No they didn't. T3s were/are insanely overpowered compared to the rest of the ships.

The balance was made in cost.

Money doesn't matter in eve due to the huge population of bots.

Therefore balance failed.
