Yeah, I suppose I am. I want to clarify I'm not bitching at you or your guild for employing Gearscore intelligently.
My position on Gearscore remains strongly negative. It's not that I believe it cannot be used intelligently (it can). I do believe it is difficult to use it intelligently because it is in fact a very poor tool for accomplishing the supposed goal: to find characters well enough equipped to be capable of clearing whatever content your group is attempting. What does 5000 GS mean for the important stats of, say, a hunter? What does 5000 GS tell you about the damage mitigation and threat control of a Pally tank as compared to a 4800 Warrior tank? Why, exactly, would a pug of 24 characters with over 5400 GS looking for one last healer to fill out the raid need that healer to also have 5400 GS?
Gearscore gives pug leaders the confidence to judge who is capable of running with a raid, regardless of class, spec, or even role (tank, DPS, healer). The fault is that in most cases that I see it is a false confidence because a single unreferenced, dimensionless number like Gearscore cannot replace an understanding of the game mechanics throughout those classes, specs, and raid roles.
