People aren't likely to stick with the CRT for very long once they can use something else, and the bruiser is unlocked after the assault... did you mean berserker? The berserker is the first available light mech, which requires better movement than the assault to use effectively, but is just as easily able to top the scoreboard.
I feel like this is just your experience, to be honest, because assaults aren't that commonly the MVP in the matches I play in. Have you tried actually playing the assault? You've been saying that other people using it make it seem overpowered, but I want to know if you feel that way when you're the one using it. I personally have to say that I'm not that good with it; I'm much better with burst-damage mechs.
Yes I meant the berserker. I always mix up those names, lol.
Of course I have used the assault mech myself. I did significantly better with the assault mech than I would do with the CR-T (after practicing/using the CR-T for long enough to unlock the assault mech, mind you). I only used it about 3 or 4 times just because it felt so cheap. Gameplay is just not engaging if all you have to do is hold down two buttons while your mech mows everything down.
I'm not saying it needs a major nerf, it just needs to be tweaked in order to put it on par with the other mechs in the game.
Also, I'm not the "typical" player that wants the game to be easy. I've never been a fan of abilities and "perks" that give you a FREE kills (i.e. airstrikes, AC130, nuke, etc.). But I do know that 99.99% of players LOVE games that give out cheap kills like Halloween candy like that. Which is exactly why CoD can copy, paste, and make millions every year. Also why most will NEVER admit when a weapon/ability is overpowered but they will use it EVERY chance they get in order to get cheap kills. I'm not implying that you (Emagas92) are like that, but the majority of players most definitely are.
