Mostly loving all of the new controls/interaction so far, especially combat is a lot less janky now and the avatar isn't juking around and twitching undesirably. Haven't had the "dead mob dry hump" effect yet either. Haven't had my avatar accidentally move when I'm trying to heal. Feels like a normal game now.
Biggest complaint is RIP afk hunting. Next target basically only targets something right in front of you, and auto-tool stops after each mob, so no more just hitting "next target" repeatedly to clear a whole area. Since that was my primary playstyle, it's a bit of a disappointment, but I'll adapt.
(edit: this is basically replaced by right-click now, and is actually much smoother)
Everything else so far is vastly superior though.
Oh, and I can't delete the stupid default icons at the top right, but I'll make a bug report for that.
if I can't hit next target on the keyboard I'm done.
