You're basing your entire discussion off 1 person? Fucking Lol.
Also: from Blizzards own MVP page:
Q. What does an MVP do?
A. MVPs promote constructive posting wherever they can. They contribute to the community and encourage polite discussion throughout the forums. When you see an MVP post, listen to what they have to say—they were also chosen for their knowledge of the game.
. Why didn't you select _____, someone who always gives great constructive feedback on X subject?
A.
Please understand that MVPs are not class/race or community representatives in that sense;
they are not chosen for their ability to criticize game mechanics and give feedback. They certainly can do this (and many do). The members of the Community Team are still your vehicles through which you should submit feedback by posting on the forums and in blog comments. We do not have a class/race representative system in place at this time and would prefer to hear all players' feedback instead of a select few.
Oops. Looks like they aren't selected like you think they are.

Basically Mvps are mvps because they aren't whining crying trolling posters. They don't "tow the line" they just don't act like dipshits either.
