I have a level 34 Marauder speccd Annihilation. I've played Carnage as well and havent tried Rage. Basically, between Annih and Carn, Carn is better for pvp 20-40 and annih is USUALLY better for pve. This comes into question because it is all about finding the right mix with your characters spec and companion. If I'm fighting mobs I use Quinn to keep me alive as long as possible while I deal DOTs and straight out damage. When I'm fighting a boss I use Jaesa because I got her upgraded armor so she now has a good amount of health while she also has good DPS. I will jump in with her and we will both be DPSing and when I get low on health I do force camo to get her aggro. When she is around 20-30 percent health Ill jump back in. Iv'e never died while doing this. Just make sure you are no less than 1 level lower than the boss your fighting...
