I mean, the antiair that basically only strikes directly over her head and is SUPER slow to start up isn't a function that I'd call good. But I will admit, I fucked up some Lancelots last night who were over dependant on the air teleport with it last night. It still loses to a LOT of aerial functions from Metera, Zeta, Gran, Katalina, and ultimately I still feel like you're better off going for the air grab.
I won't lie, once I found that LaDiva's cr.M was pretty safe, I had a much easier time. The range is bad but if they block, you're still pushing them halfway across the screen with the blockstring, which is usually enough to scare them into making a mistake off a mixup.
You just have to work SOOO HARD.
