Asian market is different than West. In WoW's Asia servers,
Raid lockouts are more frequent and there are microtransactions which helps your character like experience boost potions. But US/EU/Oceanic servers don't have these options. Now, just because there will be some non-cosmetic transactions in Asia servers, this doesn't mean that they will come to west servers as well.
Edit: It seems the raid lockouts in WoW Asia servers were changed with the new expansion pack. Thank you Vaximillian for the corection.
