Anyone else frustrated that her s.L rapid fire can't combo as an anti-air?

While it’s not the best anti-air s.L around, if she could at least anti-air with this normal and combo into itself 3 times without X-Factor she would at least be a bit better.

Urgh.

I usually confirm an anti-air s.L into s.M, but that’s after a long time of using her and playing this game. I use it as a deceptive anti-air, since the tail doesn’t have a hurtbox, and the hitbox extends out farther than it seems to.
