Posts like that would drive an amusement park out of business in a season. The rollercoasters are funded by the kiddy rides and snack bars and bumper cars. Even Disney knew that.
WoW is an MMO. It requires players of all kinds, to thrive, if only for the economy. If the game only offered raids, there would be no Wow - of it would be one server, in maintenance mode.
The irony is, the elitists, and those who copy them (the try hards), cockblock players from the higher level content, with their ridiculous demands, even for content designed for casual players, so the pool of experienced players shrinks, and then they complain about not having enough experienced players. They create a catch 22 within the game - you have to be experienced to get into the end game content, but they won't let anyone get experienced.
It's one of the aspects of the players I don't miss, and that I remind myself of, every time I think about giving WOW another shot.
I know a lot of the elitism is posturing by young kids with poor self esteem and poor social skills, i just prefer to not let them have any effect on the things I do for fun in my free time.
