The Legend of Zelda: The Wind Waker has notoriously horrible enemy AI and literally nonexistent pathfinding. If an enemy spots Link, it will try to chase him down on a completely straight path, even if said path leads into a cliff face which Link is on top of. Enemies make no attempt to avoid obstacles such as unclimbable slopes. The enemy AI is often cited as an example of the game's lax difficulty.
Your pawns in Dragon's Dogma can really make fighting cockatrices & Death suck. Both of those enemies can kill all of your pawns in an instant & pawns aren't programmed to dodge the attacks that do that.
If you're fighting an enemy who can only be killed with projectiles but you don't have any, your projectile-wielding pawns will usually spend the entire fight running in random directions & yelling that someone needs to use a projectile.
Daimon has an attack that sucks every in & kills them. Pawn reactions include running into the attack on purpose, walking away from the attack so slowly that they quickly get pulled in, standing still, & attacking the suction with their shield.
Pawns don't like running from enemies but they don't like fighting 'em or healing themselves either & they don't follow you closely when enemies are around.
