I have a lvl 18 dragon monk and my proc also is only firing off for 15-18 damage. Ive tried unequipping and relogging and stance switching but it always is now doing 15 or so damage. I have also tried various mobs just incase it was just a heavily resistent mob but same no matter what I fight its 15 damage.
yes..i'm a level 16 monk and i'm getting around 12-15 damage per proc on all the mobs i've been trying..the lower damage proc is on like level 18 mobs and the higher damage proc is level 15 mobs..
