I constantly get a brain freeze proc and yet it’s still on cooldown and unusable. Highlighted/glowing, SHOULD be able to cast, still on cooldown. Anyone else?
Flurry gets highlighted both when you get Brainfreeze and also when you get Excess Frost from the Frostfire Hero Tree. You likely got the latter and thought it was the former. An easy way to tell if it’s Excess Frost rather than Brainfreeze is to see if you have the Brainfreeze indicator above your character’s head. It can be a little confusing but it’s a limitation of the current interface which was clearly not designed with Hero Talents in mind and was never properly updated to accommodate them. They’re sort of looking at ways to fix this in the Anniversary patch but it doesn’t seem to be a priority.
