Personally I'm not a fan of big combos, but I am of execution.
I like that the right conditions must match for a big combo to be executed (not simply that you just get hit), that way it keeps them from happening often.
That said, I am not in favor of the simplicity. I think executing a combo should be based on timing and not just button mashing.
4-5 movement executions (not looping) and some great damage I think is the sweet spot.
End of the day, we'll play the game and see if it works. Maybe it'll please the mass majority on both sides.
The Marvel character list so far though is
most Avengers are so boring. Scarlet Witch, Black Panther, some X-Men + FF though and their villans and I'd be happy.
I don't have a Switch (not much time for gaming these days), but this sounds like a perfect game for it.
