Attention all you Hunters out there!
Fighters spamming RU got you miffed? Fight back with our own glitched skills, let them hang in limbo cause they didn't see the damage either. Neither did their lil' priesty back-ups. The skills work fine, they are just bugged like Fighter/Warrior Rising Uppercut.
Saw some really stunned egos in Canta this morning while they spammed laugh emotes from seeming non-damge skills.
Hope this is on the bug/glitch list to be fixed.
p.s. If you are still skeptical of the skills working, go pwn some mobs. It's just pvp/battles that hide the damage and create the HP bar glitch.
