I have found that Affliction warlocks have some issues. First off the active spell for the Affliction Artifact is not working at all. Also the Legendary Ring that I got does not give a second talent that it promises. Also whenever I respawn in battlegrounds, my pet dies and becomes a guardian that i cannot control. I have to re summon it. Also in duels I have found that soul shards sometimes do not regenerate. I found this out when I dueled a paladin who went into an arena mid way through the duel and then we redueled and my soul shards would not regen or even reset from 0. I had to relog to fix it.
