Ah, the noble burst cooldown in World of Warcraft! What the heck is that? Well, in short, it’s a cooldown you press to boost a bunch of outgoing damage. Avenging Wrath for Paladins, Recklessness for Warriors, Pillar of Frost for Death Knights… you get the idea. You press the button now, and then for a limited time your abilities get better, and then the cooldown ends. And a lot of those are getting taken off of the global cooldown with the next beta patch for Shadowlands.
Why? Because they were clunky when on the cooldown, really; it didn’t feel fun to press a button to boost your damage and then wait until you could press another button to actually deal damage. Now you can just press these buttons and start going, which is closer to older functionality for several. While players clearly have several more abilities they would prefer to have off of that global cooldown, seeing these ones moved off is obviously seen as a step in the right direction.
