This is my first real mmo so I dont have a grasp of what usually happens, but why do casuals need so much more content if they only play a few hours a week? all endgame content eventually becomes casual content so why do casuals get so annoyed when people talk about new dungeons and raids, it all trickles down eventually?

Release high lvl content = almost everyone plays it (in time)
Release lowbie content = a lot of people are already beyond it and dont need it

I dont understand why this sideways progression people talk about needs any new content at all, its already all there, its complete..

Must be hard being an mmo dev, wouldnt like that job..
