What went wrong? Is it the game or the grenre?

[Despite]

Difficult content won't make it into the game since most people prefer accessible and doable by all type of content. They simply do not have the patience to die over and over and actually learning content anymore. WoW is a good example of that as from Burning crusade and onworth it had not a single piece of Difficulty left. Cataclysm had no difficult content in any kind of way. Gated content(I am guessing that means all the reputation grinds etc?) is horrible when it is to much. WoW was feeding on that type of content and it got annoying. Everything new contained Either Rep grinds, token grinds or anything similar to that.

You're right.
Archimonde? Simple.
3 drake Satrharion? A cakewalk.
Lich King? Did it in my sleep.
Can't speak for Pandas. I quit by then.
