Im really surprised you didnt include Swarm AI Tuco ...
That was really significant mechanical change.

There was plenty that I didn't include, but that aside I just went through an entire playthrough of patch 8 and I can't really say I've had a ton of chances to appreciate Swarm AI.
In fact, I distinctly noticed it just ONCE when four goblins in the temple courtyard moved concurrently and (so far) that was pretty much the full extent of it.
