Anyone who can't kill a sunbreaker, is doing it wrong. Have you tried peregrine grieves? How about Khepri's sting? Nothing manacles? Final round headshot? Ahamkara's spine (double tripmine)? Suppressor grenades? Shadowshot? If none of the above work, try this [spoiler]Run[/spoiler] And if that doesn't work, try [spoiler]not complaining that a tank class has more armor than an agility or recovery based class[/spoiler]
