Warlocks and Hunters are the only two classes in WoW Classic with pets, but unlike Hunters, Warlocks are getting a completely new role to play in the Season of Discovery. With Warlock SoD Runes like Metamorphosis and Demonic Grace, Warlocks can be Tanks in SoD, and they're looking to be one of the best Tanks in the Season in general. But aside from an exciting new spec, Warlock players who just want to DPS are getting lots of strong Runes to try out, too.
