Give Summons their NPC alternate attacks

Just went through Malice while summoning my Lich, and saw a Lich fighter do a spin attack and an overhead chop while attacking. Why not give Summons like the Lich these kinds of attacks as well?

-Give the Daemon its Leap ability
-Give the Skeletal Footman its Stun and Rend attack
-Give the Phoenix its Damage over Time attack
-Give the Skeletal Mage Death Ray, Fire Arrow, and Blink
-Give the Lich its spin attack and overhead chop
-Give the Earth/Ice Elementals their Root and Stun attack

As for the Air, Water, and Fire elementals (I'm not sure if their NPC variants have any other attacks, though I know the Water Elemental heals)I have a couple of suggestions for both:

-Fire Elemental will cast Immolation on itself if something gets too close
-Water Elemental will cast Water Arrow to slow its target
-Air Elemental will use Chain Lightning

I hope these abilities would scale with their level in terms of damage and duration.

 

Someone just told me that summons originally had alternate attacks. Then give them back but scale them so they aren't super OP.
