Warlocks have to spend a soul shard to summon a demon. That shard is refilled fast when out of combat, but in combat it takes a while to get it back unless you get really lucky with procs. We also have to stand still to cast the summon, unlike hunters and dk's that have their pet show up instantly.
"Fel Lava on Argus will no longer damage pets." just watched my pet die as an unholy DK soo yeah ... don't think its fully fixed yet or maybe it should of been tagged "hunter pets no longer take damage from lava on argus"
My Felhunter continues to take damage because it seems to like standing behind the Imp Mother, and my Voidwalker took damage, even though it wasn't standing in the fel pool. Nothing raining down from the sky, either.
"Tassia Whisperglen, a stablemaster, has traveled to Argus."Does anyone know her location?
