Why is all endgame-level open world content daily/weekly?

[Redemption]

Better questions would be, What purpose does having a daily/weekly lockout accomplish for MMORPG's? What would happen if the sugguested request by removing those lockouts effect overall game design? Why would the dev team add these lockouts only to MMORPG and not single player rpg's also? Most these if you've played mmo's for along time already know the answers its an necessary evil its to prolong the content so dev's have more ample time to develope more content like 2.3 in basic term's. After the release of the newer content if you've noticed the older content gets unlocked and a new lockout is put into place and the cycle continues.

Then why are you able to do dungeons in an unlimited quantity for the same rewards (mostly)? Why shouldn't we be able to do different hunt targets as many times as we want for myth, sol tomes and hunt credits? Make it so you can only get the sands/oil weekly if they must but don't limit the use of the content when the rewards are the same things you can get in an unlimited quantity from dungeons (in the case of sol tomes, no matter where you get them theres a weekly cap so that is the same as well).

This is not an open world MMO. . .

That is debatable to some extent, and that is also why I am asking to see some changes. They have an overworld, they have people who have an interest in doing interesting things there. If they don't want to do it then they don't, there is still a valid point in requesting it if they are open to it.
