I was disappointed in Legion when there where so many new demons but our options, at least for our main demon, remained unchanged. The only option for a tank is a void lord with or without armor.
In Legion Demonology Locks was able to have a permanent infernal or doomguard, tank or ranged. Why not bring back the permanent Doomguard as an option, or better yet let us power up. As of this expansion we’ve bested A LOT of Doom Lords. I want a Doom Lord…or an Eredar. We can already summon an Eredar Tyarant
