Am I suppose to fill those gap with Mind Flay, thus delay the VB/MB case by may be 1sec or so due to GCD. Or am I suppose to just do nothing and wait to cast VB/MB as soon as they are available?
The priority list of Icy Vein and other sites mentions nothing about this, they only say use Mind Flay to fill, and interrupt it whenever VB/MB come off cooldown. Which is all good if the cooldown remaining on MB/VB is more than 1.5secs, but if the cooldown remaining is shorter than that, I end up delaying the cast due to GCD, no matter how much I spam click.
So...what am I suppose to do here? Do nothing and wait, or Mind Flay away?
