You're mistaken.
You're thinking of people competing for the top of the mythic raiding ladder. People who play 'professionally' if you will. Yes, i would ignore these as well.
There are scores of people who play all day and you wouldn't know because they don't make a bleep on the mythic radar.
These people actually are the ones consuming the most content in the game because they don't spend their time on ONE element of the game (not to say some of the mythic competitors aren't also achiev/mount consummers)
These people usually will have a pretty good idea of what are good and bad ideas for the game.
Love him or hate him, and god i don't like his persona, but when he sits down and talks 'seriously' about WoW Asmon has actually a pretty good hindsight of the game and what people like and don't, being that he deals with lots of people on a daily basis and gets a good sense of what people want to see and what they don't, what they like to do and what is a chore/ serious hassle.
