There's a lot here that I like, so I won't attempt anything close to an exhaustive list. I'm just here to say that I LOVE spells not critting.
I'm singling it out because something tells me it's a really iffy proposition whether this change is ultimately retained. It "takes something away from players," which WotC is incredibly hesitant to do, and when Crawford mentioned this particular change in the video he went out of his way to emphasize that it was a playtest and not yet an officially adopted change—whereas, in contrast, I get the sense that quite a few of the structural changes are pretty much set in stone at this point unless feedback is overwhelmingly negative (as opposed to changes specific to particular feats, races, etc., which I would bet are all more tentative).
But I love it. It lets players of martial classes have something special that's iconic to the game, but most spellcaster builds won't really suffer all that much from it.
