From my quick read-through...
-In my opinion 4 ability score increases/feats is too little, 5 should be the minimum.
-Paladin is a lot more palatable now that there's no alignment restriction. And the moving special abilities around makes it easier for other alternate "oaths".
-Barbarian finally got it's own subclasses too, though I think some work needs to be done with the Totem Warrior.
-Don't like the removal of skills, I know they're trying to make them optional, but to me they're an essential part of the game.
-They still don't give good examples of how you could use the Hinder action.
-Humans are still overpowered.
-Still don't like half-orcs, they need something else other than just being tough as their theme. On the other hand those half-orc stats are good for an actual full-orc race write-up.
-I like that mage traditions, along with many other things actually do stuff beyond 10th level.
-For the Monk of 4 Elements, fire seems to be the poorest of the 4 choices on all of them except maybe disciple, where it's just an OK choice.
-Obviously it seems like Fighter is where they put most of their energy into developing. I like the variety of the paths.
-I know they don't want to show all the different subclasses/paths/traditions/whatever yet, as they're still trying to find out "Is this the right direction?" but most of them shown so far seem like steps in the right direction.
