I was trying to get more survivability then damage since i play with two others who are mostly archers. In short im trying to tank.
Im not doing so bad solo, infact im not really having any issues at all, though i do think i could be doing better. Elemental Equilibrium feels like it could help, though im not so sure... i keep wondering if it will make things more complicated, so i keep holding off.


Any ideas or suggestions on where to go with this build?



Thanks!
