NO ARENAS. God crossrealms and arenas is what destroyed wow PvP.. and I dont get teh fascination with open world PvP since its gonna be unbalanced on 98% of the servers anyways.
I've opened about 23 bags by now, in my second I got a chest, after that I got none. RNG rewards are simply retarded. Period. I prefer Wows system over this any day, atleast its consistent...
