The best game brainded AI moment was for me that Ansur the dragon had 500hp left from 600 and he jumped to the casm. He just did suicide. So skipping two turns is not so bad .

But yes you are right it just happening to many times.
If someone watching the feedback videos that I am making its clearly visible. That kind a 10 % of the combat that I faced in Act1 the enemy just skipped the turn and did nothing.

Why? Because they don't have tools specifically casters do this after they used all 4 spells that they have.
