usually there's no real pattern but there's some tendency I noticed so far, in short I believe the enemy had hidden aggro value which determine their attack pattern but here's what I know so far :

1.) enemy tend to target anyone who used brave chain, if at beginning of rounds someone used brave chain then chance he'll be ganged by enemy that turn.

2.) enemy tend to target your big gun for the boss. suppose to say that the enemy mob is Lancer and the boss is Rider, if you're carrying Assassin to hit the last boss then usually the assassin HP will decrease faster than other member, not unusual to be ganged by the enemy.

3.) enemy tend to target the one that could kill for sure, someone with low enough hp to be killed by ganging on him. bonus point if the servant NP is nearly ready, you can be sure that the enemy will kill him whenever they got the chance. the aggro will reset once you fire said servant NP.

Those are the pattern for usual circumstances, meanwhile there's special circumstances, that is special programming to the AI so that they behave in certain pattern. All I know so far is :

1.) Zerker Lancelot and MHX will always target Artoria face, if there's two they'll alternate between them.

2.) Penthesilea will always prioritize greek male.

3.) On some event some AI will have special programming, there's that famous anniversary boss that will put OP support (Merlin/Waver/Tamamo) as priority, there's that Enkidu from summer race event that will always hit divine first, there's the male hunter Medb, and I forgot the rest.

I'm sure there's more quirky enemy, the cue is that they have certain reason in lore to behave that way.
