Why?A fully geared player can ruin your fun too :D Much much successful way to play great than the gear score is to understand your race and class, to understand what can do your spells, abilities, talents, perks ... and to adjust your ability's rotation to your playing style.I'm saying that as player who is playing WoW almost from the start of the game.And i have many situations like that - a trash geared player is the best DPS in 10 man heroic raid with triple better geared other players.For me the gear score is just noobmeter, nothing more :)

I fully agree that a high geared player can be a massive noob and a lower geared level that knows what he is doing can play better. But there must be some kind of gear measure. Let's say the first dungeon needs you tube level 10 and you apply for a party, but another player joins and he is also level 10 with level 4-5 gear and he got to level 10 by killing chickens (it's an example :) ), you just won't have enough power to clear the dungeon no matter that the guy knows his spells well, they won't have the firepower needed.
But yeah if your gear has, let's say, 100 score and the dungeon needs 70, you can party up with a bit lower score players.
