There is a time in every monk's life when he or she sits down and says "Why does the XP system work as it does?". Because it's human nature, that's why. I don't have the right to question other monks' votes on my nodes, just as nobody else has the right to question the way in which I vote personally. As long as a monk doesn't downvote with 90%+ of their votes, then their decisions are their own. It's why we have ++/-- votes, not a system where every upvote and downvote requires approval by 5 other monks in order to be effective. I am of the opinion that downvotes should be used sparingly, but then again, whose business, other than my own, is that information?

In short, I also questioned the XP system once. Back when I read a little too much into the voting system. I have since then learned that the XP system is flawed in that it takes into account human interaction. If you let a human being decide how to grade something, each person is going to react in a completely different manner.

In super short, just don't worry about it. It's not as important as it may first seem. What can I say, life sucks :)
