Gold Standard WoW ? What the...!
Like others have stated WoW had less endgame content than this game. And please please don't forget that people weren't able to run Molten Core flawlessy because of server lag/crashes/freezes until 2 month after launch. Here you can run the endgame content already without major hiccups. After that WoW released content at least 4-7 month apart. You had the occasional 2 month content patch but in all the running years of WoW it happened like 3-4 times.

The typical MMO after release is a baseline where a wide variety of content can be added on to depending on the players reactions and needs.
