What if summons were ultimate abilities? They would scale off of the highest attribute and would be viable for Stamina and Magicka builds. Assuming an ability can have more than two morphs, the Daedric Summoning ultimate could have 5 or 6 morphs. Each morph would be a separate summon with different roles and abilities. Since it costs ultimate points, it would be balanced against other ultimate abilities. Since it's an ultimate, it doesn't need to be a toggle.
