That's awesome that pc players get to learn how to play their class properly

It's not cheating, would you say that stopwatches are "cheats" in field tracking? Because, they're basically the same. Nowdays in a lot of MMOs this kind of things are supported even by developers. Square Enix doesn't allow this in their terms of service not the team, Yoshida himself said he doesn't mind players that use these tools (Such as Advanced Combat Tracking). It's something normal for someone to wants to check their perferomance with some real numbers.

But everyone has access to stopwatches, but I said loosely, anything that gives an advantage over another player that can't use it, could be deemed "cheating".
