Another thing is that the AI behaves differently in the various events.
The tournaments mostly follow the block 2 pattern, and in my experience the attack 3 block 1 pattern doesn’t happen very much anymore when in that particular situation unfortunately.
CoT event AI routinely follows the block 4 pattern
Infinity battles can utilize the block 4 as well but they also for me at least rarely swap out the 1st dino even when they have class disadvantage.
The more you play the more you will pick up on the various AI behavior for the different events.
The individual PvE is strange sometimes it behaves very much like AI and other times it does bizarre stuff and you would swear there was a person behind it.
