Hey Blizzard.
Please consider to take a look at Fire and Brimstone for Destruction Warlocks.
Right now it has its own somewhat short Global Cooldown, which makes it super clunky.
It even bugs out once in a while if you land exactly on 1.0 embers or 0.
Removing the GCD will make it such a smooth play aoe’ing and improving macroing it aswell.
Theres already a damage penalty using the ability.
