I did a weeks worth of pvp *at lvl 50* Thats 1 weekly, 7 daily bags, and maybe 3 warzone bags* Im nearly completly gear in that 1 week.
BUT your complaining with something that is ment as a lotto!
THE NORMAL way would be to reach the required valor ranka nd buy using the commedation! So your complaining about a system bent on chance. Not the way TO gear.
The normal way is based off wows ranking system, so much more grinding, less payoff... HERE THEY GIVE YOU PAYOFF at the chance of luck. Sorry your unlucky, the system isnt flawed, your want for shiny objects without understanding the system is whats flawed.
