I just feel that "complex" and/or "rewarding" fights come down to the actions they permit among players and depth of consideration they reward, rather than anything directly to do with the efficacy of the AI itself.
If a mob has an interrupt, for instance, I want that to be a constraint/point of available optimization for party coordination and positioning, rather than just something that prevents the use of hard casts in any tight situation (need to heal now or tank dies) [just reduces available complexity in a span of moments] and/or something you make sure to bait out onto CD before doing anything risky [chore-ish, though not awful if neither too long nor too short a CD].
Make it so you can body-block mobs and said interrupt is a melee, though, and you can easily have those benefits and more, with none of the situational losses to available complexity. You could maybe even bait a hard-cast heal to peel a mob towards you (the healer) before using an instant-cast spell or ability instead anyways, or have a Paladin feint a Clemency to take the interrupt early when he's not about to Req anyways. Etc., etc.
