after playing 3.3 for a whole bunch today against Ankoku, Bowyer, and Levitas,, i'm really starting to like the way this game is feeling. But as much as i appreciate you trying to make the melee top tier return to top tier, there are a few balance things that i believe need taking into consideration.
First off, i believe there needs to be less hitstun. There are way too many stupid combos that shouldn't work in the least (i.e. fox usmash > jump > double jump as high as you can > uair an hour later because they were at 90% after the usmash).
Also, something seriously needs to be done about sheik's ftilt. It has this nice ability to auto combo like, the whole cast from 0-70 including followup. Things you could try would include increasing the base knockback of the attack so it always hits reasonably far, or you could try like, doubling/ trippling the cooldown lag of the attack, so it would be timed more like melee.
Also, it seems like some characters (lucario) can actually gain speed by jumping out of a run, not just preserve speed. Not that this is disbalancing, it's just kinda weird.
Pikachu's quick attack also seems like it can't sweetspot when angled downward for the 2nd part. Didn't actually thoroughly test that to see if it's the case or if it was just us sucking the couple of times, but that's rather not good.
W/o the edgesnaps any more, edgeguarding becomes much rougher. In brawl system, you can't tech by pressing R before being hit, nor can you tech during hitlag, meaning, for a lot of recoveries, someone like peach can just dsmash at the edge, it'll stagespike and KO guaranteed because it's impossible to edgetech (and avoid in most situations). The ability to press L/R before being hit but still w/in the tech window in order to tech would be an excellent addition to this game.
Something that might be addable to make the cast more diverse would be to add DJCing back in for the characters that could before (peach, ness, yoshi, and probably now lucas). Speaking of lucas, consider speeding up the come out time of his grab to make it normal grab speed. Lucas seems like... really bad, and this would at least give him some advantage.
As far as most other stuff goes, great job guys, i'm really liking your product, and I hope you keep up the good work.
