Eh, sure, why not? From a semi-casual point of view, this is what I'd like to see from each.
-What exactly do you want from Story Mode?
Cheese. Glorious campy cheese. Oh and for every playable character to get a turn so I can get at least a quick feel for them by playing through the story. This includes playing the villains, too. It would be nice to have a branching path where you can choose the order of doing stuff, then come back together for a finale, but doing it like SFV, only with more cheese is fine.
-What exactly do you want from Arcade Mode?
10 fights of increasing difficulty. Fight 9 is Ultron and Sigma, fight 10 is Ultron-Sigma. Simple enough, really. Should have many difficulty levels, but the point of it is to try out characters and teams against a vide and unexpected variety of CPU controlled foes. See how it handles before committing to Training Mode.
-What exactly do you want from Vs Mode?
I rarely use it, so I'll just cop out and say whatever the competitive community thinks are great quality of life additions. They know what those are better than me. Vs. CPU would be great to have, of course.
-What exactly do you want from Training Mode?
Just a completely off the wall suggestion, but you know what would be awesome? To be able to import from a replay. You get into a situation in a fight that you don't get or don't know how to defend against, you import that into training mode directly and try it out.
Oh and a slow-mo option, right down to frame by frame movement, maybe SUPERHOT style. The game doesn't move unless you input something. To quickly test if what you're doing is even possible or not. Then you can worry about timing later.
-What exactly do you want from Mission Mode?
The most important thing would be doing things that you normally wouldn't. Basic combos, sure, show off those, but also show off weird properties of each character, show off the edge case scenarios and such.
-What exactly do you want from Collection Mode?
A model viewer would be nice, with the ability to pose them in any of their moves. Useless trivia, Smash trophy style, too. And of course alternate outfits and music and all that. A music player would be nice, too.
-What type of ranking would you prefer in Ranked Matches?
Early placement matches! If you're good enough for a higher rank, you start in it after 7-10 fights. Maybe not top ranks, but let good players jump ahead early... to get rid of them in the lower ranks. Nothing is more discouraging to a casual player than their first 10 fights being completely unwinnable to the point where they'd do better by putting the controller down rather than trying to fight.
Some sort of seasonal ladder might be nice, too. Maybe have a player level (which should NOT be grossly inflated by doing ridiculously easy singleplayer content, looking at you SFV!) and the rank as two different things. It's just pretty bar filling, but that's nice. Even if you're on a losing streak, you're still inching closer to next level up. Which... really doesn't do anything, but increase a number. Bigger numbers are better than smaller numbers!
Again, this is from a semi-casual point of view. They had me with X being playable already. X in a silly cheesy story with Marvel characters is just a bonus.
