Patch 2.2 has been live for a few days already, and for the most part, it seems to be working well. However, that doesn't mean there aren't a few hiccups in the system, and unfortunately, Warlocks bear the brunt of one of them.
Warlocks are reporting that their Conflagrates, or those of their teammates, aren't just removing their own Immolate spells, but ALL Immolates on the target. One can see the issues that could crop up in raids and what not, but this behavior can also create problems in the Battlegrounds too. What a mess.
Hopefully Bliz gets around to hot-fixing this and the sound and disconnect issues asap. I'd hate to think we'd have to wait for 2.3 before seeing (and hearing) things change.
So c'mon Bliz. Give a damn. Get moving.
