Iron Games HCS H2A Event - Legacy Thumb Stick?

How can the HCS H2A Columbus tournament be successful while the Legacy thumb stick layout does not work in H2A currently? Should I assume that not a single competitor plays with the Legacy thumb stick layout?

I understand 343 is aware of the issue and expects me to wait until early next week for the next update but I can’t express my anger regarding this basic movement function being broken enough. Basic game testing 101…failed.
