why are people so resistant to constructive criticism about the game?

[MistakeNot]

My constructive criticism is unlink the the content and areas maybe not the dungeons from msq progress. At least the non current expansion. Nothing bugs people more than having to do 800 or so hours of content to reach semi relevant content with their friends. Like at least dragon skin maps content.

My counter-argument is that new content is in no way more "relevant" that old content.
Those 800 hours of content? They are most of the game.
