Yes, what annoys me the most isn't the AI doing things like auto not hitting your stun immune guy, or always going for the kill because they can see hp bars. It's things like animals not acting like them in combat, and the like. Make animals fight using numbers and brawn, people with smarts and tactics, making things fight differently can add a huge amount of variety in the game. Having a single mastermind is at best lazy and at worst incredibly boring.
