I'm having a quick blast through with a new character and it feels like a pretty decent update already. The amount/quality of loot is dramatically different, practically no trash, loads of useful rares right out of the gate, I'm at Homestead but already holding on to several build modifying items.
The evade skill is nice, doubles up as a little movement skill as well. I don't use it too much because I've gone pet Shaman/Occultist so I'm not really in the firing line, but it seems very strong. The new potions are fine, they have strong effects and just enough of a cooldown that they aren't just an easy survive button bosses/uniques.
The automated auras are nice, my skill bar feels much less cluttered already. The option for bigger health bars is pretty good too, it's much easier to keep track of pets. It's hard to notice some of the skill changes so far, my Briarthorn feels like it's hitting like an absolute truck though.
