How exactly Force Potency is affected by the global cooldown?
Sometimes, I'm running my healing spells around in a WZ, and I see FP is off cooldown. It is in-between spells (global cooldown is still counting), so I pop it for my next heal.
Now SOMETIMES it activates perfectly. Sometimes it does NOT. Sometimes I spam it and it just say "no ty. Wait for GCD to be over, then we'll talk." GCD ends, and it activates just fine. In this second scenario, it does not start another GCD (which, as I understand it, is intended).
What is the deal here? It's a small thing, but I like to maximize my healing done, and that split second I have to dedicate to hitting that button first (instead of spamming Big-Healerance) is time wasted.
