Disagreed. You just compared one game's mechanic to another game's mechanic for which it has been on multiple times proven that it's (still) broken.
Compare it rather to the ladder of subcaps: frigs, cruisers, BCs, BSs.
These classes scale well. While higher classes get more DPS, they also get gimped in other areas so that their vulnerabilities can still be exploited (lower top speed, lower alignment time, higher lock times, signature resolution ratios,...). How many times have you seen (awesome) vids of groups of frigs or awesome solo cruiser pilots take down BSs? Too many times to count.
Your logic by comparing it to a broken ship (OMFGhitpoints, OMFGwinbutton, OMFGjumpdrive, OMFGdps, OMFGblob) is thus quite obviously flawed. Hmechs do not have impossible to destroy buffertanks, tanks, dps or anything. Currently they're just gimped because of some general fear that they could become OP. Probably that fear comes from seeing Hmechs in big groups, but ppl tend to forget the interference issues within these groups. Also that fear might come from people not having proper skills to pilot them, while "certain" groups completely dominate the battlefields with them.
Last I saw a small group of lights and assaults took down a mech easily(http://perp-kill.net/?m=view&id=8824) and I have yet to see a lone Hmech that would survive that hound squad.
This game has more of a problem that people seem to think that in an equal number of players fight between hmechs and "everything_else", the "everything_else" should somehow have at least 50% chance of winning and thus every hmech gets prenerfed or nerfed. Now tell me, for a bot that takes "racial" robot control 8 or 10 (in mk2 variants) and needs advanced robotics over 8 to play properly, why would that class be balanced for a 50% win scenario? Seriously are you all ***? If you want 50% win ratio, then make it cost the same in EP and NIC as light bots and then it can be.
tl;dr: Personally I see no reason to gimp Hmechs (and no, I don't pilot one) with accum issues. There are many ways to counter hmechs in this game, starting with all types of ewar available.
And yes to comment smokey, his fit gets around the accum issues, but leaves the bot with so many vulnerabilities it's just laughable. And even he needs a support bot following him for "just in case" scenarios.
The bottom line is that Hmechs currently fill 2 roles: either supported by secondary chars (dualboxing or teamwork) for close(r) range engagements or long range glass cannons. Let's compare it with eve again: how many roles can the battleship size group of ships(meaning all different BS sized ships) fill? Fukcing any and all and they're still not OP.
Stop this stupid jealous naive *** about hmechs already.
