One of the things that has increasingly struck me while reading peoples' accounts of the new LFG system is the frequency with which people cite getting kicked from groups due to a low gear scores, or scathing comments from other players on the extent to which they are being "carried" after damage meters are posted. Now, while I don't believe that this is an overwhelmingly common practice (most players have had positive experiences with the dungeon finder, and I'm one of them), it's still a problem. People have complained since the beginning of WoW about damage meters and the jerks who spam them, and we've all seen our fair share of the unhappiness wrought by the misuse of GearScore, but this is different. At no point in WoW's history have so many players who don't know each other from Adam been tossed into relatively intimate 5-man situations with the total freedom to be angels or asshats to each other (and, speaking of the Adam we do know, even he's given up and started to expect some bad play in his PuGs).
I am about to propose what I know is a radical departure from the standard gamer practice of reducing someone else's total worth to a number that, ideally, is lower than yours:
You're happier not knowing.
