Random thought of the day:
Meta Knight is pretty fun to play as in Brawl (camping aside). Even M2K himself has claimed he plays like a Melee character, which is why he is so attached to the character.
So I was thinking, maybe it would be cool to keep his moveset and feel identical to his Brawl incarnation. I haven't been following the project TOO much, but last I remember, you guys increased his weight so that he was a fast faller. That's an interesting idea, but it makes playing him feel really weird. He's obviously meant to be a floaty, as he's a puffball. It looked like he was fighting against gravity with every jump, lol
Of course, there has to be a catch: Make him Dark Phoenix. A glass cannon. The project has taken ideas from fighting games already (super-armor-all-day Bowser, Lucaryu), and I think it would be really cool to have this broken character that has a **** ton of tools, is super fast, tons of jumps, has a great recovery... but dies at 60%. Wanna use the banned-tier character? Gotta take the risk.
Not sure if it's entirely feasible, but just wanted to throw it out there.
