Stuff that actually helps new players:
*Alternate dash or run that gives good mobility without need to wave dash. Otherwise there is going to be a huge variance in mobility between new and experienced players.
*Input buffer. I don't know if Marvel Infinite has it but if the game still has some link like combos then it's still going to be difficult to pull off combos for your average player.
*An actual Tutorial mode. There has to be a mode that teaches all these VS game mechanics. Super jump, advancing guard, tag mechanics, DHCs, bursts, stones, aerial rave, magic series, OTGs, air dashes, throws etc. The tag mechanic itself requires a massive tutorial by itself.
*Matchmaking that actually works and different online modes that aren't just Ranked/Casual with Lobbies.
*Single player mode that feeds players mechanics/moves/options piece meal so that players aren't overwhelmed with having to learn to play two characters from scratch.
There is probably a ton more things but we know from history that stuff like auto combo doesn't really make it easier for newcomers.
Stop acting like the goal is to get new players to be competitive players and start acting like the goal is TO GET PEOPLE TO BUY THE GAME AT ALL, have fun with friends fucking around in SP modes so that people that do care about being competitive can continue to get updates and characters.
Because we have had these mechanics in FGs before and they didn't lead to better sales.
Most FGs have crap single player modes and don't teach mechanics/moves piecemeal. A FG single player mode has you playing against the AI with a full character. That's so bad for a new player.
Imagine if Capcom made a DMC game but gave you all the moves from the start and then put you against final boss tier enemies from the start. Veterans would love that shit but new players would get overwhelmed. That's exactly how it feels to play a fighter for new players. How do you expect people to have fun when they need to be able to play two characters and be switching between them on the fly?
Stuff that sells FGs are visuals (which Marvel is lacking right now hard), roster (which is probably going to be good long term), good online, great tutorials and great single player modes. What doesn't sell FGs is auto combo stuff.. we have that stuff around for years.
