And this is why you are burnt out.
Why already are you exalted with every faction?
You really needed to be? You don't have that much self control that you HAVE to do every single faction you can every day to get to exalted with everyone as quickly as possible?
Instead of smashing your face into them and coming to the forums and moaning and bitching about it, how about maybe you do one faction per day.
This is what I am doing (well tbh I do do Tillers every day) and I have not once ever been close to Valor Capped and I have capped my weekly valor every single week since hitting 90.
