I’ve noticed a pattern in problematic AI behaviour.
I’m sure we’ve all seen a bot walk face-first into a heavy attack from a Chaos Warrior or similar and they don’t even move, flinch, block, or make any attempt to survive, just present their face for the axe and you’re then down a team member.
This seems to be entirely down to the bots only responding to certain events if they are the target of the attacker.
It certainly feels like the AI relies on some form of unseen “handshake” between the bot and enemies in the game, but only once they are targeted by an enemy.
This would also account for bots straight up ignoring enemies that are attacking the player e.g. you’re trying to heal and something agro’s you only for the bots to stand around and watch you get hit.
Now what I also suspect is that one bot is all bots.
They aren’t treated as individuals.
This is why they can sometimes all stack on top of each other and perfectly duke a monster and take no damage, and other times (when the monster is targeting a player) they can’t dodge at all and get killed.
