Warlocks are STILL not spawning with their pets in BGs. The basic and proper functionality of respawns only works about 20% of the time. Far more often than not, warlocks respawn with no pet. If you guys can fix this, just make all demons cost no soul shard and instant cast in BGs for the first 10 sec after respawn.
Also respawning doesnt clear effects pets had before respawning, and if they have any effect, they don’t respawn with full HP. It took over a year for the HP bug to at least some times work correctly.
