The audience that left the tripping fest to die in favor of Melee and Project M. Yeah, people like watching Smash 4 right now, because it's a new game and the meta is developing. But it's going to turn into a defensive game, sooner or later, due to the awful air dodge from Brawl, shield stun being stupidly low, shieldgrab being as great as ever, and the unpunishable roll and sidestep. It's probably not gonna be as boring as Brawl, but Melee (Or Project M) will top it in the end.
As far as unpunishable, I don't know; I'd chalk that up to the 3DS controls being downright awful and people not wanting to go for hard reads/gimps/general punishes.
But rolls definitely are better in this iteration.
Offensive capabilities have actually been heightened due to lower landing lag, and shield pressure might become a real thing again (not to mention multihit moves are now viable with the near absence of SDI).
There are still a few true combos and the overall speed has been increased (and the game almost looks decently balanced), but in terms of the technical ceiling and overall character potential, Melee and Project M are still at the top, and there's nothing wrong with that.
My only issue with Project M is the balance; it's wonderful to be playing a decent character, but I feel like a slight nerf overall would actually help the game a lot.
It just feels way too easy to combo compared to Melee and some characters get away with stuff far too easily (Kirby's dash attack comes to mind with its hitboxes finally vanishing a few frames before the entire move ends), and it just gets boring to me after a while.
Melee isn't well-balanced, but at least comboing felt like I was actually putting in work rather than having everything pop my opponent into the air just enough to convert into pretty much whatever.
Smash 4 is going to be a good game in its own respects, especially once people get controllers they're truly comfortable with.
It may not be the best (I can't forgive them for taking Wario's tires and fsmash), but it's certainly a fresh look on the series as a whole and it's more than worth it to give it a real try.
By the way, bait the airdodge.
