Way to make a big deal out of someone missing a word (yay, zoom quote). I'm glad you got some enjoyment out of that, kinda like a kid with a stick and a pile of poo.
And it does have range if you
run and grab, along with Sonic's speed it's deceptively large and can catch people off-guard. And that's the entire point of what I said, everything Sonic does is to catch people off guard, and with a dash grab you can do that (unless you like running past people giving them time to react). Sonic is one of the best grabbers in the game, all because of his speed. Besides that, I find it much easier to grab with Sonic than I do with Marth or Ike, and a few other characters I play with (except Charizard, grabbing with him is easy).
Maybe great range was an overstatement, but like hell if it isn't a great thing to do (down/back/up throw rock).
And the down B thing still seems useless to me, just seems like a normal edgeguard or a spring cockblock would suffice if they're far enough out for you to have to use spin/whatever. I still think you're trying to make something situational into something more mainstream. Believe me, I've tried spin dash/charge chasing, and I have a lot more success with just normal edgeplay. If I smash/hit someone off stage, I damn sure know that I can run to the other side just as quickly if not faster than turning around and setting up an optimal speed spin charge.
