Lol, I don't see why it has stayed. Equip a different weapon and attack with that, see if it does the same thing. Mine's never stuck that long.
After talking with a GM it might be a bug IDK he put it in with QA team or some team I already forgot >.<, Along with some other abilites not using the correct animations.
Get the JAb Glyph.
It's not like we use our weapons for anything other than jabbing.
