1. It's still in development, their jobs aren't making the game for the 50 guys (maybe) so that's why certain characters aren't there yet
2. Goku is top tier unless you're talking about this game being taken seriously and it is taken seriously they made it with the competitive players in mind so there's little start-up or end lag which makes you able to do a ton of combos
3. And what characters play like garbage? They are all fun or really good unless you're just bad at the game which is fine
4. How is the roster directionless? Just because they don't have the characters you like make the game bad?
It's an in-development product still, but I'm allowed to criticize the choices made.
And the choices just feel out of wack.
Going for purist favorites? Then whey the anime characters? Where's GANONDORF? And why is Bandanna Waddle Dee the only character from the past 15 years on the roster?
Why the lackluster Pokemon selection? And why is it exclusively the "cutesy" ones?
FE had two characters from the start in the main series yet is just sitting there with Marth-- odd for a series Nintendo now considers a major franchise (with their apparently being plans for Ike and Roy that got scrapped).
Related to both FE and Pokemon: why limit things to characters already in Smash? It's a fangame where everything's made from the ground up, so why not be more creative with the choices?
Both series have a crapton of major/popular characters that are easy moveset potential. Zoroark could be a feral rushdown character that creates illusions for both offense and defense. Leif could both be a callback to him initially being considered for Melee and be an all-rounder weaponmaster type character due to his promoted class being able to use every single weapon in the game.
Heck, this could be said of other series' representation in general-- why Sheik instead of, say, Midna?
I tried Isaac, Lloyd, and Sora. Isaac felt funky as hell (maybe if they had gone with a more traditional moveset design and had basic sword normals with synergy in smash attacks and specials he'd have felt better) and both Lloyd and Sora just felt banal and unimpressive.
I guess to TL;DR things it's a fangame that's too predictable/wastes too much of it's potential while simultaneously just having some real WTF choices to it.
Instead of embracing its nature and going the full nine yards, it feels like an awkward mish-mash of too derivative and too out there.
