Momentum should be a general mechanic, more so than in Melee where running momentum existed. Another thing is that we need the option to turn around in the air while requiring a longer input for falling back or forward, so that you commit to it.
For the push, I think that should be whenever a grab is countered by another grab, not just after a throw to prevent chain grabs. Another thing is that tether grabs should be untechable and that the input for that is Forward-Z while neutral Z is a regular grab.
Thanks. What was my reasoning exactly?
Anyway, I'm gonna think of different playstyles for possible characters.
Saki - Gun Slinger (Noel from BlazBlue would be an excellent reference.)
Takamaru - Projectile based like MvC3's Arthur, but with Iaido and counter attacks. He would be something of a glass cannon.
Tom Nook - Fighting by not actually fighting. Playstyle would be high risk, high reward.
Ghirahim - Footsies and mixups by using his daggers, buzzsaw daggers, and 8-way teleport.
Isaac - Keepaway character preferring to win by eliminating movement options to force to opponent to SD. His Move attack is an example of this.
Lip - Zoning by using blocks from the sky as air defense and for wall juggles.
Krystal - Mid-ranged fighter with a lot of combo potential.
Little Mac - Rushdown and in your face. Has evasive techniques to dodge projectiles and initiate counter attacks close up.
Toad - Lightning grappler with a strong tech chasing game. Has some of the best mobility in the game.
Bowser Jr. - An in and out character with great mobility. Uses his siblinbs in a way similar to Marvel vs. Capcom's assists. Overall, a very obnoxious character with no one right way to play as.
Megaman - Mobile projectile character meaning he can run while shooting. Can use a command grab to copy an opponent's special. Which one exactly depends on the character.
Kumatora - A very mobile, unpredictable zoner of sorts. She uses PK Ground to get hitconfirms into devastating combos that are high risk, high reward while using her mixups to bite away at the opponent. If you've ever seen C. Viper in action, she's pretty much what Kumatora would be.
Midna - Surprisingly a grappling character thanks to her hair. Her traditional fighter "equivalent" would be
Vice from King of Fighters. Wolf Link is not present.
Dixie Kong - A mixup character with a strong poking game.
K. Rool - A living wrecking ball of a character. Has a rushing attack that is designed to absorb attacks up to a certain level of damage. Balrog's rushdown might be comparable.
