I see no reason to why Control Undead should dismiss our ghouls in Unholy spec anymore, especially since we already have the ability to have more than one pet in that spec with the talent “All shall serve”.
When questing in the world I always try to grab some of the interesting undead NPCs in the while in the other specs because they add a small dmg increase and it’s a fun little aspect of the Death Knight class, to be able to control undead. So how come Unholy spec which actually is ment to be the one where you have undead under your control is gimped when you use this ability?
You lose a big chunk of your dps because your ghoul disappears and the NPC undead usually has much lower dmg and can’t benefit from Dark Transformation…
