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