I agree with the 1st point, the annoyingly difficult inputs don't help SF4 either.
I disagree with Brawl.
Link, Ganondorf, Jiggs, ROB, Lucas, Luigi, and Falco
are ALL boring as **** to play as in Brawl. PM makes them magical (well most of them), and a lot were more fun in Melee when they were more cloney, mostly Falco and Ganondorf, this is simply to prove that not thinking things through when building a character can have dire consequences in how they play, this is why I'm against dumb choices like PacMan and skeptical about MegaMan (love the series don't get me wrong, but jump-and-shoot man is a bit of a tough fit for fighters), the Melee clones played better because they were built around a playstyle that had been thought out, and just changed a bit here and there. The Brawl de-clones are just ****ing strange to play as, I don't like them. This is why "A de-clone Roy like Wolf and Lucas would be best" is a stupid statement. Roy would work if Roy is built around a unique and interesting strategy, not of he's given some different moves for the sake of being different.
Oh, sorry if I come off as condescending, I'm not directing this at you, I'm just ranting...
