Arrow Storm is overpowered as hell in PvM and really makes the game un-fun in party play, because Rangers steal the show. Half-baked players with +4~7 gears can do 200k damage, while players with +12 gears and, god items, and MVP cards can only be about par to that damage, if not falling way short of it. That's pretty unequal.
Please change the hat to do something with traps like you promised, or at the very least, make it like Performer's broken hat that doesn't work.
