I still wonder how Blizzard then kept an ever increasing player base when the content was only one difficulty, challenging - and moreso, it was the only content! Quite odd, really? Or is it simply that the developers only want to make content that everyone can see rather than content that should be seen?
I'd wager my entire account that way more people are attracted to the idea of raiding than people recognise, the drive to be special is strong in almost everyone, whether you like that or not.
