Obviously, people are allowed to feel however they want about Ultimate and its DLC, but sometimes its good to take a step back and really look at what we have. When I first got into Smash speculation in 2011/2012, if you had said that in two more games (well, three technically, but two of them had the same roster) we would have this, you'd be considered optimistic at best:
-76 characters in the base game, 88 with DLC
-Every vet (including those previously cut)
-Rosalina, Bowser Jr. (with Koopaling skins), and Daisy
-Little Mac
-Ridley
-King K. Rool
-Animal Crossing characters (this was a popular idea thought to be impossible)
-Fire Emblem characters beyond basic lords (Fire Emblem was actually considered underrepresented in Brawl)
-Palutena (with Dark Pit as a bonus character)
-Shulk
-Pac-Man
-Mega Man
-Simon Belmont (with Richter as a bonus character)
-Cloud Strife
-Banjo & Kazooie
Because of this, I have a hard time really feeling disappointed with what happens next with DLC. Nearly every core request of the Smash fanbase has been basically answered, so I just want to see where the ride takes us. If you look at the Ballot, the only two characters who did particularly well but are not in Ultimate are Bandana Dee and Geno (who still could be coming, as far as we know). Is that to say Ultimate is perfect? No, but nothing is and this game is damn close. Even if Wave 2 has nothing to really scratches my itch, I find it extremely hard to think that Sakurai and the dev team didn't have fans at the forefront of their mind.
