After playing World of Warcraft for 15 years, I started becoming increasingly bored and disgruntled with the game. The game being grindy and repetitive is no real surprise, I mean it's an MMO. But the one thing that was really frustrating was paying monthly for a subscription and a huge chunk of cash for an expansion, but still having extra stuff flashed in my face all the time that was simply not possible to earn in-game. Mount skins, cosmetics, miscellaneous stuff that is only available in the Blizzard store. They also began adding loyalty items that require being subscribed every single month, and doing repetitive, extremely boring stuff on top of the other repetitive boring stuff, so basically double dipping on your grind, which really isn't fun.
