I hate the "X is easier to use than X" excuse. And to use Christie in a certain way is not even that easy. Core fighters... Even if Christie is easier to use, your character has amazing tools to beat this character out.
Ayane isnt even THAT hard. You guys act like she's the Akira type hard and she isnt. She just has a few hard to pull off strings and managing BT and normal stance. Other than that, I never have any trouble using Ayane. Sure Christie gets away with her BS online but if you want to use Christie like lets say QueenJakhehio, it is not as easy as it seems.
