I know; why do you think I stopped? Nowadays, I just correct people on stupid misconceptions like Falco having windboxes on moves or using Fair to approach since somehow, it's a good idea to approach with a move with 25 frames of landing lag.
It's fine to use Pit as a template, but what's not fine is saying stuff can steal his thunder which ironically he doesn't have because Dark Pit has an electric element move, Electroshock Arm, not Pit. There's a point where you run out of moves and concepts e.g. Lucas's Fair can be called a weaker, less punishable Zelda Fair or how many characters jab, the actual move, because it's such a simple move used in almost all martial arts. You can't undermine a character unless you specifically make the character the same, but worse compared to another. Case in point: Lucina. Lucina's credibility as a fighter in Smash is probably the lowest; Dark Pit at least is interchangeable and Dr. Mario at least feels different and has different strengths and weaknesses compared to Mario. Even Pichu has more credibility as people can at least acknowledge it's a joke character while Lucina's a joke who shouldn't be one. Giving a character a move similar to another doesn't really do much if it functions differently with the rest of their kit. Diddy technically has Mario's Uair and Falco technically has Zelda's Nair and ZSS's Uair, but they interact and work with them differently compared to Mario, Zelda, and ZSS. Rosalina technically has Falco's Uair, but because of its hitbox, different angle, and lingering frames along with how she works and moves, it's almost an entirely different move despite similar frame (which also suggests it shouldn't be killing like that, but it does 'cause Rosalina).
Also, this is disgusting:

See, when I think of grapple-based characters, I think of King from Tekken, Hakan and Abel from Street Fighter, and Raiden from The King of Fighters and you know what's okay about them? They actually have to work for their grabs. Hell, let's add ZSS, Meta Knight?, and even Ness and Diddy both pre- and post-patch. They work for their grabs and they convert dangerously, but Luigi? Low risk, can spam, has among the fastest grabs with low end lag, and massive rewards even compared to ZSS or The Freaking Ice Climbers and Brawl Triple D.
