I do like act 3 in general, there are some really good interactions like
Orin keeping you on your toes and abduct a party member. She abducted my bestie Lae'zel and killed the child in the camp and made the thread very real. Raphael's HoH was hilarious - a boss singing his own themsong. Freeing the prisoners underwater was nice, you had to be very tactical and efficient to get everyone out and it felt so satisfying.
The locations are great too. I don't really click with Gortash. The other two have simply more personality to them, while he is the sleazy politician. Jason Isaacs is great as always though.
Some quests are a bit confusing, like the
clown quest. That seems to be the only more mindless fetch quest around and I've decided to not pursue it. The artist quest didn't really update proper for me, so I had to look up, what to do next, it was always o e step behind in my quest log.
I'm just about to start endgame ( couldn't play as much as I wanted due to real life and a virus that struck me down) for the first time, so can't say much about that.
