General Battlemage

Dark Shock Glitched I went on my Battle Mage I made during the union patch (not sure if its the problem, cuz I see other people using it) and I tried using Dark Shock yesterday, and it would say "You may not use the skill yet" I waited a few mins, and tried it again, but it would say the same thing So i thought after today with the revamp and SP resets it would work, but it's the same anybody else have this problem? or does anyone have a solution to this?
