Hes 100% spot on. If you want it, earn it. If you gotta farm it, farm it. All these cosmetic things are not so important that they need to be given because you continue to try thats a handout thats unnecessary. If its a low drop its not ever going to be impossible.
The example of the reins of the heavenly cloud serpent is never something I farmed I think I have killed him 5 times outside of MoP? Got it from a unclaimed blackmarket box for 80k after buying maybe 20 boxes and getting nothing. I rolled those dice everytime and spent tons of gold buying boxes. Thats RNG no guarantee and I personally dont want to play a game where all the hard to get stuff is guaranteed after X number of tries thats boring as hell.
