Storm caller is by far most OP. The melee is purely insane, regen health upon activation of super, basically blinds people, you have a form of blink to go all over the map, the grenades are good, landfall and super on a control zone can wipe a whole team left and leave them with enough super to keep going, etc. it's -blam!-ing overpowered. IB is a joke right now, I'm a good PVP player and I'm fed the -blam!- up.
