Yeah, moving ASI to backgrounds seems like a big bit of tradition to kill. Floating ASI is one thing, having it based on background instead of race seems...almost un-D&D like.
Savage Attacker. I was wondering how long it would take them to apply advantage to more than just d20 rolls. Wonder why they don't just call it advantage. Weird.
Tavern Brawler. Monks have a few good reasons to take this now.
Long Rests. Good to see some sanity has returned. They finally made it explicit that combat interrupts a rest, not the ridiculous one hour of combat reading.
Short Rests...despite the phrase appearing a few times in the document, it's not actually defined here.
