This is all going to fall under the banner of "thoughts by a guy that kinda sucks and hasn't even played real people yet" and I'm not making any real assertions as to what is good or bad.
She does have a dead spot between B2 and her close normals. I know it's a given that you want a character to have every range covered, but it's fairly narrow distance band that seems like you should be able to make someone work for.
If someone really, really wants that spot, then harass them with the shield until they find a way to get in B2 range, then swing at them with that or use D2 if they try to do it airborne (D2, D2, BF1 is super flexible and easy). If they do start to get in MB BF3 to force them to start climbing again.
If they keep trying to get into the dead zone you may be able to take advantage of their persistence and creep in to meet them so they are in range. If you are willing to make a gutsy read, you can MB shield toss which causes them to step forward into range and continue with a full combo. I'm also guessing when they are in the dead zone is probably is about as good a time to use an armored B3 as you are going to get.
I don't see anything wrong with the idea of giving her a full time air dash. I can't imagine it would drastically improve her in a way that would cause any issues with rocketing her up tier placement.
It would sure be nice to kill the random on trait. 4 directions + neutral = 5 and she has 5 traits, so .... I don't think that would make her all that much better. It would just let her adapt to the MU situation a little and drastically reduce the friction of using her trait. If they had to limit it somehow by like, only letting you pick one per round/match then that would still be better than dice rolls.
She does seem to need meter to get much of anything going. MB shield toss is needed to get into most of her damage, and you can't really toss out a random Bash without it. I don't know that that is unusual though, and I don't recall feeling starved for meter thus far, so maybe I'm full of it there.
One thing I am leery of is that her main combo pattern has two somewhat tight commands early on. Something I like to see in a combo is where the risky stuff is stacked at the end so if you do drop it you still get most of the damage. With WW, you better not drop it before you get your wall bounce or you are out a bar, a turn, and a lot of "I almost had it" damage.
Anyway, that's probably the closest thing to insight that I will ever have. We will see where things go. I don't have to worry so much about picking winners. It's a for fun gig for me, and B11 shield loops, into BG bounce, into wall bounce amuses me a lot. I doubt I will have an exclusive relationship with WW (loyalty seems like a bad idea in IJ2) but I think I'm keeping her around. I just kinda dig the chick.
