Skimming the pack, I've noticed quite a few changes. Rogues with expertise dice, fighters can take sneak attack, new monsters in the bestiary... There's also some subtle changes, like the fact that expertise dice now refresh at the end of your turn. Makes sense.
I'm really curious to see how things work out in actual play. Some of the monsters in particular feel a bit strange, like the hydra. With the number of hit points it has, and the rechargeable 'regrow two heads' ability, is it ever a good option to lop off a head instead of dealing damage? Also, the dragons don't look scary...
I'm really not a fan of the generic specialty names. I hope those are just placeholders.
