I think Demonology should use more than Felguard

I wish they’d add more variety of Demons that Warlocks can use but overall I believe that Demonology Warlock should prioritize more than just the felguard.

I like the idea that they get a special demon but hate that the spec that is demon centric is forced to use only 1 specific demon. I think the demonology spec should have the option to empower the others so they can pick which one they like to use
