So, in case any of you are curious, here is some knowledge compiled from me and my friend's play time of Ultimate. Some of it will be obvious but thought it would be important to mention anyway.
-Shield feels closer to melee shield. It's not nearly as good as it is in 4 and shield stun is ridiculous. Shield grab is apparently not as good of an option anymore. So overall, shield is pretty bad and if possible, use maneuvers like jumping or crouching to avoid moves.
-Everyone is bad offstage. Like honestly, getting back onstage is as tricky as melee. Ledge isn't the best option anymore, so landing onstage is gonna become a good option again.
-3 frame jumpsquat makes every character feel better, especially snake.
-Pretty much everyone with a sword is busted as hell. Link is probably the worst sword character and he's still good. Roy is the best one despite his lack of landing options.
-K rool good. Real good. Gotta force him to recover high if you want to edge guard which is really tricky.
-Most importantly, combos are back. Chaining hits together is back. You can bring someone from 0 to 50 or 60 if you're good enough.
