Affliction warlock, DOT focus!

Hello everyone. Why dont we have a real affliction warlock? Like change corruption as it is now to a regular instant cast DOT spell. Like rework corruption to work like it does in wow, maybe add curse of Agony, make it as it usually works butt modify it damage wise to fit heroes of the storm. But if not any guldaan changes. An Undead warlock with the focus on the damage over time and singel Target fear would be epic!
And a shadow Priest would be cool too, maybe make anduin multi class? :slight_smile:
