Enemy Mages wont attack

[Elizinator]

in my (heavily modded) game, im noticing that enemy casters above a certainly level almost never cast offensive spells. they simply run around buffing and healing themselves, often summoning, but never actually attacking.

 

most pertinent of my mods are ASIS to add spells from damn near every magic mod out there - Phenderix, Apocalypse, Better Magic, etc - to copious NPC. again, ASIS to make Deadly Dragons, SkyMoMod, and Higher Level Enemies. im not sure exactly WHAT they are casting, but only rarely is it a damage-dealing spell, which means i can run amok amongst casters, hewing with my sword while they try to heal. it is immersion breaking, and no challenge whatsoever, whereas if they WERE attacking, id be toast.

 

any ideas? has anyone else seen this before?
