Please FIX Warlock Rain of Fire stacking
Warlocks are pretty much abusing Rain of Fire stacking AoE with Mannoroth's Fury....
Since Rain of Fire has a bug that stacks with each other (which it shouldn't) warlocks kill in massive AoE just by placing 7-8 Rains of Fire in 1 place and deal 19k each so that's about 90-110k each tick from ALL Rain of Fire at once or about 990k when they are all done... I've seen a lot of warlocks abusing this thing and laugh at my graveyard when we spawn to do that again. He has about 100M damage done in less than 2 minutes just by abusing Rain of Fire with Mannoroth's Fury...
Please Fix this ASAP since Battlegrounds are one sided if a warlock has full grievous gear and also abusing this bug.
Please don't just read this post because this is something big and important. Impossible to do anything against that since it's instant cast, stackable, crits a lot since every destruction warlock that abuse this use Dark Soul, and uses Mannoroth's Fury....
I hope that you respond and try to fix this ASAP because it's really not fair to come with PvE skill and dominate because it's bugged.
Sincerely
