Congrats. Welcome to learning about a GCD of 0.5. I didn't think I would have to talk about the GCD but here we are. And so what, every class has the 0.5 GCD. Grats. They also have oGCD attacks too! Shocking! Every. Single. Class. Has. To. Deal. With. Latency. And. GCD. Stop using it as your defence.

Well most classes have longer CDs on their oGCD abilities. That's probably why he feels it the most with DRK, since we do use Dark Arts as often as mana allows us to.

What I personally don't get is why he doesn't macro Dark Arts onto the def cooldowns, since that's essentially what he was asking for initially.
Dark Mind w/o DA is so weak that you'd never use it anyway, so no big loss taking it off your bars and replacing it with a macro'd version.
