I think that we do great damage and can take plenty of damage. Dont forget just being in cover we get 20% melee and ranged defense and are immune to various things from interrupts to pulls and enemy leaps. I believe that marauders/sentinels need ti me nerfed not necessarily there damage but instead in shields like come a shield that reduces damage by 20% and damages attackers in turn that increase duration as your hit another shield that reduces damage by 99% force camouflage reduces damage by 4% and so on. Come on i know they got to be at certain range but they pop their speed boost on a sniper their up their in no time they constantly pop shields and when you die they still have at least over 40%of their health
