So, I am told that you get a 50% bonus while leveling a class when you have another class at least two levels ahead of them, and that certainly applies when you have one class at level 50.

I assumed that this exp bonus is automatic, but to be honest I am not noticing a significant boost on my WHM, even while FATE grinding with rested EXP. I saw someone say something about syncing in order to get the extra EXP, but I am not sure what that means exactly.

So, what is the deal?
