The purpose of the game is to win, not be flashy, this seems to be her most optimal combo and I would see no point of doing anything outside of it, and the fact it uses no meter is GOOD especially since the full variant does 1/2 health. Erika can spend her meter on B-Escape.
Sure it may not look terribly interesting to see the same combo, and I agree that you should probably master some of her tricks with her assist, but poking into confirming into that combo is pretty legit.
EDIT - Erika has seen the least amount of changes during the post release patches, but she suffered many nerfs leading up to the game's release (Cyclone Chain is so useless now) so while I expect them to nerf her soon, I'd rather they not :<
