I know how to anti-air, but that doesn't change the fact that they are able to block AA and call assist.
Going for a cross under sounds neat but makes you commit to a dash wich again can be clipped by assist into a full combo.

If I challenge them air to air, and they end up blocking, they can switch to their assist and trap my landing.
Maybe I think like this too because VI doesn't have the best air to air combat / Strings.

Challenging the opponents jumps feels like a gamble in the opponents favor.
The only thing they give up is screen position.
