Your opinion does not represent of the majority. And blizzard already did recycle old content. That is 5 man dungeons. Blizz buffed their loots and dmg/hp increase as well.
And about the time, you are right. Thats why I said, rotate them, so all old raids are not up. Like warfront.
Raid bosses are fun, challenging. Just give us more content to do after you are finished with Nyaloth raid and stuck for a week due weekly reset. I want to progress further with raiding. Not stuck with one week, and forced to do recycled content 5 man dungeons. Give us options. Nothing wrong with that. I hope you understand me
