Toning down her durability would just mean that characters who can already fight her can fight her better where as characters who lose to her badly will still continue to lose badly to her. Characters like Magneto and Deadpool would rejoice but someone like Iron Fist and Haggar can't really do much about it anyway.
They should tweak the fireballs in AV which is the main problem. Having fireballs come from behind you it's lame as hell, characters with no real air stall options have to sit there and eat the chip with no reliable way to retaliate.
Morrigan is at the very least a good litmus test for how ill equipped some characters are in the game. This should be using her as a way to buff characters so that they can at least fight her when she has assists + AV up.
Yeah, I feel like there's this gap between characters who have aerial mobility, and those without. All of the She-Hulk and Frank West resets, the Ultimate Web setups, everything is pretty much "anti-non-air dashers". These characters are also screwed by incoming mix-ups. It would be healthy for the game for every character to get some form of aerial maneuverability.
I'm not sure what Astral Vision would do if Soul Fists didn't come from behind the opponent though, haha. One must also not forget that Astral Vision is
not easy to set up all the time. It's not some amazing 4+0 move like the Devil Triggers or Sougenmu, it has like 30 total frames of startup. It can't be used for unblockables like Zero, it can't be used to gain ridiculous mix-ups like Vergil, it can't be used to gain a meterless Hard Drive that's positive on block, etc. All of the buff moves are pretty ridiculous, so it seems Astral Vision needs to be, too.
Also, I think Sougenmu is actually superior to Astral Vision in terms of lockdown and chip damage. Sougenmu locks you down for its entire duration, and when I watch health bars go down it looks to be more effective than Astral Vision as well. One day someone will run that Zero/Morrigan/Doom combo and folks will see how good Sougenmu is.
So would having the astral vision soul fist's disappear if morrigan is hit asking too much?
Or having all soul fist disappear if morrigan is hit?
I would be okay with the former, but not the latter. Mostly because Morrigan's entire rushdown game is based on the fact that you can Soul Fist, fly cancel, and then air dash in, and the projectile will protect your approach. It balances out how awful her mix-ups are without a pinning assist. If Soul Fist disappeared when Morrigan takes damage, characters with good anti-airs would whack her without fear as she approaches.
But again, I just don't think Morrigan is a problem. I really don't, and I'll stick with that opinion until someone wins with Morrigan in a major without Hidden Missiles.
