I'm fine with vortexes and think everyone should have one to some extent. That being said I also think risk/reward should be a factor. KF's vortex is a perfect example, hers requires meter for the overhead so if you guess right she loses a bar. The only one I have a real problem with is Batgirl's. I think both the overhead and low options should be unsafe and punishable, because hers requires no meter and she can do it anywhere on the screen. This on top of having great corner damage, interactable countering, and anti-zoning. It's fine to have all these tools but at least make it have a risk/reward factor.
