And citing beta stats is just as bad.......Those max level raids? Max gear? Optimum players? Gonna say probably not at this point, at least on the gear/levels. So you can't compare a class at this stage. Classes are balanced at the top of the heap, not while leveling.
You clearly said Warriors are not topping at max level, and you can clearly see they are, and its fucking consistent.
Giving them even better gear will just extend that lead.
