Meh, I wasn't in a ball very much in 2.6 'cause it always just sucked, but now that Nair hits faster, and side-B can be cancelled faster(used to be that you spent at minimum a frame in the air before being on the ground, really, so the timer would always reset one frame later. This has been fixed), so I can pour on the shield pressure, then WD behind an opponent and go for a grab, or jab if they're a character with a low amount of jumpsquat frames. Oh short hop blast attack to get above them, and then side B away or over or whatever, the options are pretty fun and blast attacks screw with your opponent, even on shield.
Spin spin spin, moonwalk bairs, moonwalk ftilts, I spend so much time moonwalking. Sonic has so many different options out of his ground game - and that includes spins. Fast mobile hitboxes that can shield poke, or just JCGrab out of sideB if they shield.
Also if you hold B from the ground and do the full SideB hop, the timer passes before you hit the ground so you can DJ and waveland before hitting the ground with your SideB, which can mess with your opponent's timing if you condition them to react to your spins.
Also I just have fun with UpB out of SideB. Floatier characters can be caught up in the spring and can be Dair'd wonderfully.
Completely conditional, but my buddy was playing a Mewtwo. Shield poked with SideB, he tried to escape up, and I JCUpB my Side B and we both go up. Dair him, he DI's into the spring, I LCancel and Spring again, catch him on the way up with a Uair for the kill.
3.0 Sonic is just fun, and being able to react faster and without that horrifying bug from 2.6 holding his spin maneuvers back I think he stands a much better chance than before.
I wonder if they fixed his Dair physics so he doesn't sometimes just get stuck in air, immobile, after using it. Y'all know what I mean - when you get hit by an attack that doesn't cause much hitstun, and you input a dair, and Sonic just... doesn't move like he should? Hate that glitch - exceptionally prominent in Brawl 'cause lolwhati****stun.
