With things like this 
they only care about $$ while the game is still full of bugs.
The subscription model is completely outdated, there are no other games besides WoW (and final fantasy 14 which copied the same model) with that subscription method, the only reason they get away with this is because to this day they still have no competition.
If you want more examples, take a look at the customer service. Back in the day it was THE BEST, they would even contact you in game and they would help you with anything you needed. Now you have to wait a week for a bot to respond you and it will never resolve your issue.
So the more money they have, the worse service they provice, you know why? Because WoW is not a game made with love and passion anymore, for the people running WoW now, the game is just a fruit that they are going to squeeze until there is no juice left.
