Oh I know xD I think they'll add it to be at least 10i frames since I mean you could step or block it but she also has a throw and that already makes it hard to accurately try to defend against when she has those other options
It's 2i tho, so by the time you see she's in the air she's already doing the attack. It's not like Kasumi's 9P where her options are her slow mid punch slam and her high kick and her throw, I think Phase 4 could afford to have her P+K option slowed down so that it's easier to react to
