I think that stopping a match mid-battle would be kind of inconvenient unless it was player vs CPU. Consider whether they'd be in the air, damage, etc. They'd have to pull it off just right.
And something I think should have changed is to keep the characters at the speeds they were in Melee. I got used to Marth being a speedy little bastard when I played him and used that to my advantage. Now all of a sudden he's slow? Same, to a lesser extent, with Link. Sheik was okay though. (Those are the only three I really play.)

Well too bad we're not getting another smash game anytime soon. My only complaints go to the stage builder and The Subspace Emissary.
