There were already complaints about AI targeting lowest AC. It's not entirely stupid move. I have myself often targeting enemy mages in games because they can cause alot bad blood during fights. Wizardo are mostly squishy unless guarded by some powerful spell. However AI should adjust their tactic when there is some bottleneck like doors. It would be cool to have AI not jumping into fight like headless chicken but going sides and trying to clear the pathway 1st.
