The more arrogant people seem to be on the internet, the more pathetic and otherwise creepy they seem to be when they expose their real selves. Just a personal observation.
As for MvPs in general, I don't see how they're any different from regular posters, in fact the overwhelming majority of their "serious" posts don't seem that helpful at all. Most of it seems to be defending blizzards changes from whiners, which is trying to stop a tsunami with a grain of sand, you just gotta ignore it.
Not giving anyone advice to ignore a tsunami if it's headed straight for one's face, but you catch my drift?
Just look on the first page of the uncommon guide submission list in the mmo-c forums and you have more help there than all the MvPs put together.
