She doesn’t have anything like Morrigan’s j.HP, Jedah’s j.HK or Ultron’s j.HP where you just air dash and it crosses up and overheads at the same time while leaving you plus to do it over and over until it hits. That’s the main thing keeping her out of top tier for me. She has no scramble way to open you up without resources or a special move like most of the other top tier 4/8 way dashers. Even the one way air dashers like Chun have better unga bunga overhead crosses. Crossup overheads that can easily fake cross up and land in front also.
The changes to the way air dashes and flight work in Marvel Infinite allow these moves to be abused more than the could in 3. Captain Marvel is like a Marvel 3 air dasher in Marvel Infinite which means she’s stuck having trouble abusing cross up overheads and with the new system there are no more rapid fire lows to keep people sitting for frontal overheads.
Absorber allows her to play like a mini big body, but you have to put on absorber first and people with abuseable heavy buttons/specials/supers can still beat the armor. It’s not MonHun hyper armor where you have to launch cancel, use your surge or grab her (before she tags out and becomes throw immune) to escape.
The other issue with absorber is that 2 of the better neutral based surges beat the armor clean also. Power Surge and Soul Surge both beat the armor clean and can easily tag off of into combos (power surge can obviously combo solo easily with most characters). Meaning there’s at least 2 stones that make her absorber less effective just with their surges. That’s why I think Power Stone is Captain Marvel’s best stone as she can add an extra layer of unga to herself if people are using tools that blow up her absorber.
At best in pre patch she was best IMO as an anti reality stone character. Now that reality stone got nerfed, don’t really see what she offers that’s worth top 10 or really makes her a big part of the meta. She’s also only really had one relevant tournament run with that Nick Jones guy (who used Power Captain not surprisingly) and she’s been ghost otherwise at events.
