Patch is amazing.  I love it!
UI changes very welcome, nice work.  Group stealth, ungroup all buttons are very welcome.  However is there a Lock button for the UI?  I have pulled a few things off the bar.
Love the new animations and the improvements to narration.
Finally the Barbarian is a brilliant and fun addition.  I like that you guys left the Exhaustion mechanic on the cutting room floor.  I was hoping you would.  it's a terrible mechanic that should never have been put in 5E.  No doubt someone will QQ about it.  I look forward to making fun of them.  
Also major props for not releasing the Paladin.  I can refill my supply of the "tears of Pally Fanbois" which I use to spice my food.  It's a rare delicacy.  
The revamped throw mechanic is extremely well-implemented so far.  I look forward to having some major multiplayer shenanigans with that one.  
Finally the game world feels much more stable and polished overall.  Wunderbar!
