before I got geared, I would get rolled by anything more than 1-2 enemies. Your best bet is to stick with a big crowd, stay back, and pick off melee at max range. make sure you use traps, that ice trap really sucks, especially in towers/bunkers. Feign death also works on me, sometimes in a heated battle, i see a hunter drop, and i move on, and dont notice him hopping back up and continuing to fire. make an arena team for points and get discounted deadly gear. it will take time, but once you get your resil up, you will start to last longer and pwn more.
