There are other things like guild rep

In wrath, people who were not morons used GS as a FACTOR in choosing people when running pugs for raiding or 5 mans.

There are other things like guild rep, knowing the person, their class, how they're gear is set up (gems enchants spec etc).

Then there is that word that everyone likes to throw around: "skill."

Your "skill" can't make up best wow gold site for the fact you cannot mathematically pump out enough dps to finish a heroic boss off. Gear = higher dps even if your a baddie.

The vast majority of complaining about GS discrimination comes from people who 1) don't have the proper spec, 2) no gems/enchants or the wrong ones, 3) the wrong stats on their gear, 4) no situational awareness and die constantly. You were not picked up or kicked because of your GS. I'm sure everyone has run into that dk who is UH spec but dpses in frost presence. You want to tell him "hey if you switch you will do more dps." But you know he will be all like, "STuzT*%!! upz, I kanoz meh dps is Higher than urrrrz." So we don't bother.

The point wast Gear score or Item level is not the be-all end all. It is a tool that people can use to evaluate your readiness to enter into the next level of content. Besides everyone knows that DPS takes NO skill in pve. Hit a few buttons and don't stand in %@@%...durp.
