It looks like they want to move away from stuff like Attacks of Opportunity, and that they want to bring back more judgement calls from the DM. Both of these are good things, in my opinion. I'm interested in how they describe the Fighter as not improving his To Hit rolls, but getting other abilities instead. I suspect at least some carryover from 4e is part of this. I'm curious about this, and I really hope it will be awesome when the game is finally released.
