I really feel it would be a fantastic indicator of experience and could give you an idea of someone's skill, but then there's ghosts. I can't remember exactly what I found out they're worth, but I remember t was between 300-500. So that means if I was 4100-4300, but I never farmed the ghosts, I wouldn't be let into your group, but if I had, I would be allowed to raid with you. Same me, only difference is if I farmed the ghosts. It's kind of a dilemma.
