My team is at 47 atm, been doing lbrs lately with my lock.
I found out, xp rate sux for lockboost after zf, but the alternative, leveling solo/questing is even worse. Been thinking of leveling paladin to 70 first, then boost em with him, but as for now, iam sticking with brd/lbrs.
Edit: The thing that makes me go, think of it, FUCKING 4/5 elementals, HEROIMS. GOD, its gonna be awsome :B
