To the self-important baddies who insult people on their servers and on these forums for setting Gearscore requirements for their PuG raids. In response to the mutual back-patting, and kudos I have seen to those who reject using it, and try to ostracize those on their server who do. All I can say is... deal with it.
Gearscore is here to stay, and it's a good thing.
No Gearscore does not tell you if the person you are considering is specced correctly.
No Gearscore does not tell you if the person you are considering is gemmed/chanted properly.
No Gearscore does not tell you if the person you are considering is just in high-end PvP gear.
No Gearscore does not tell you if the person you are considering is just plain stupid and bad at their class.
But it does save people like me who PuG on my alts often A LOT OF TIME, weeding out fails, as opposed to the old way of doing it (checking on armory, or inspecting a person in front of you piece by piece, doing the math in my head to tell what their stats are).
And yes, despite the elitist mantra of Skill > Gear, that still does not = Gear doesn't matter. I don't care how pro you think you are, I'm not taking you to my ICC PuG if you have a 4kGS. Right off the bat when I see you, I can tell you that you don't make the cut, without wasting a moment of my time checking out your lvl200Heroic epics, and blue off-hand.
Just because I use gearscore doesn't mean I don't gearcheck. Every person I invite, either I or someone in my guild inspects people to make sure they are at least competently gemmed/specced properly. And the best part is? If someone has over a 5.2k GS it's almost guaranteed they are good, otherwise the other GS whores on my server never would have taken them to get carried to that level. Bads are weeded out on the server, I save time pugging. It's a win win.
And that's what it comes down to. Everyone on here and other forums and in trade chat QQing about GS, are in reality just the bads of each server, who are upset that they aren't BSing their way into pugs to get boosted anymore. Suck it up, and stop sucking and GS won't matter.
