They need to find a way to detect XIV Alexander and ban people

[Sarevok_Thordin]

This is already possible, google ffxivalexander mod. It should be disabled on dev lvl if not intended if intended it should be made baseline.

AFAIK the devs of this warn you against going too far with this if you compile it (It's all open) as the servers can detect if you are doing skill requests far beyond what you should be. All that thing does is compensate for lag for oGCD animation lock, allowing for classes like MCH to be playable at higher ping.
