Most people don’t quit games over p2w. That’s the truth of the matter. Blizzard could start selling BiS gear in the WoW Store for $150/piece and after months of uproar on the forums they’d still have 95% of their players. That’s just the way it is.

You can see this in the way Western players have accepted more and more pay2win features in their MMOs over the last decade. You can buy gold in WoW and GW2 - the latter even letting you buy the rarest BiS legendary weapons for RMT bought gold on the auction house. In ESO “gifting” item store products for ingame money is allowed by the TOS and common. There are more and more “convenience items” that make gameplay and especially farming significantly easier, essentially making them P2W from an economic standpoint - in WoW you can now buy a portable auction house for $600 of gold, something most players will never earn ingame, and save yourself a huge amount of travel time.

Truth is, the genre has been going in this direction for years. Korean games are merely the most egregious, because they import their own local mechanics (principalling buying items that increase roll chance on upgrades, coupled with item destruction if the process fails).
