You build anything from the foundation up. You're asking them to put high end furnishings in the penthouse when they're still plugging holes in the basement.
This game will gain and keep more members for having good low to mid-level content - and the players who are still demanding more high level stuff will be the ones benefitting in the long run. Why?
They will have more people to group with.
The game will have more of a budget to churn out content with.
Expansions of every sort can be pushed out faster or with more content cause they can afford to increase staff.
Just churning out high end content to keep the few people busy who've capped out 7 characters per server won't do any of that.
They're doing a good job of shoring up all aspects of the game. They're doing it as quickly as they can. They're doing it in a way that hopefully will actually grow their options to do more over time.
Its time to stop the "me first" myopic vision thing - and start looking to the long term health of this game.
