I've played as a marauder since beta and will always play as a marauder but I only recently switched to carnage from anni after 1.3. I gotta say I love it compared to anni, the burst is rediculous and if I have a healer on me it's GG.
I will say tho (about nerfing/buffing marauders), There has been a huge uptick in the number of marauders in warzones since 1.2, slowly at first but now It has gotten so bad that I am not suprised to see 5-6 marauders(on my team) in 1 warzone. Does this mean we need a nerf? No I don't think so, just that other classes need a slight buff, not all mind you, I still get my *** handed to me by certain classes.
I will say too that I think the funniest thing is being pounced on by an op dps, after you trinket out of his 2nd stun and just light him up as carnage, he is probably thinking to himself "W.t.f. just happened" Love it.
