I'm not a fan of dodging, light mechs, etc ... kinda a tank guy. But the point of tanks is you build them up so no, you can't dodge, but you can take a few hits and still fire back. Then along come RMs and totally fluck that up. My jug, effective HP 120K (Rank 6.6 with a 6.3 pilot and all) killed by one hit? GTF. Now that *is* cheating. Incompetent Devs now? Maybe the guys who started it, and designed it are gone, leaving incompetent fools who are trying to turn it into yet another bullshit arcade game.
Rear attack damage is generally what kills MOST mechs, not specifically damage of the RM itself.
The ONLY time RMs will be a real problem is when the Legendary Pilot comes out for it, IF one does. However, due to the possible backlash of such a Pilot i imagine its damage potential will be nerfed from the start to be in line with the EPIC pilot, but its HP bonus should widely be untouched.
