I want to see 2 or 3 special attacks for each player aside from the normal A/B attacks. These either have a cooldown time or are charged based on amount of damage dealt. When ready, you hit a button on the screen and you unleash a move with less power than Final Smashes, but more than regular attacks.
I also have an idea of a whole set of abilities that every character has access to (some possibly being unlockable). Before a match, you choose two or three of them to have at your disposal during game. These are switched in real time mid-game. These aren't moves, but conditions (the only similar thing I can think of is Pokemon abilities). An example would be having resistance to projectiles or a one-time cushion to a move that would send you flying well off the stage
I hate to be.... hatin'... but feels a lot like loadouts and custom characters. I just mean, sure you could add super meters, abilities and custom character things... but that ( i feel) would bog the game down. This series has grown, and is great, because of its simple fast-paced fighting. Along with that, it has deep fighting strategies and a few of its own. I feel what makes this game great isn't the wacky items and amazing stages & soundtrack (although it does help... a lot) ; it's the simple control scheme that drives you into a fast and complex game and doesn't let go.
But i can see the appeal of those things... i guess what i'm saying is... put in a vanilla mode for me.
And that comment goes well with my next statement,
Speed it up a bit, SSBM was criticized for being too fast, so they slowed down SSBB ( jump physics were slowed, items were slowed, and combos were a little bit slower making it easier to chain together). Just meet it in the middle, slower than SSBM but faster than SSBB.
