You can literally go into the WoW Shop, buy a couple of WoW tokens and effectively wallet warrior your way to KSM or KSH with a few million gold. World of Warcraft is literally pay to win thanks to this. What Blizz should be doing is banning boosting entirely.

This game has a serious elitism and gatekeeping problem, to the point where it feels like the only legit way to climb is to surrender your wallet.
