Will the model of content change in 4.0?

[Xyno]

@OP: What are you actually looking for though? Just saying that current content is boring to you doesn't point out much of a direction by which to stop being boring, and what you've mentioned in alternative wouldn't necessarily be any different from the style of current content. Anything more specific?

Almost 4 years we have all these cycles. It means, that even a little changes in the period of cycles or changes in their length of life will be very positive for the players's minds. Also, the content can be droped for some years (for example till the next addon), and when it will return, players will be happy and meet it as new.

Variants can be different. Right now we have some MAJOR kinds of content and this content live in a cycle (alliance raid, hardcore raid, 4-dungeons and another)
1) SE can try to change this MAJOR content more often. For example, we had Crystal Tower (raid alliance) in 2.x. In 3.x SE could change it for something new and in 4.x alliance raid would come back. Or we had 4-dungeons for roulette to farm tomestones- it is the MAJOR way. In 3.x SE could change it for another kind of activity
2) SE can try co make the cycles not predictable- make them shorter or longer
3) SE could more often create new types of content to fill the bigger cycles of the MAJOR content
4) Another variants

For example, Diadem. As we all can see, SE has no problem to admit, that the first version was a total failure and send Diadem for rework. I think, that Diadem can be a new MAJOR type of content, where SE can put many different types of the main cycle activities
