Gearscroe is a measure of your potential, not your skill. Far too often I see people complaining that they can't get in to things because they don't meet some arbitrary gear score. Look, I feel for the undergeared skillful player as much as anyone, but bottom line, if you're decked out in all ilvl200 stuff, youre not going to perform beyond the best of the best as they were in naxx.

That said, I also have a particular impatience with people who can't be bothered to up their GS from daily dungeons. It only takes a week or two to get up to ICC appropriate numbers, and bottom line, if you don't put forth the effort to gem/enchant your gear, I don't think you're going to have put in the effort to know your class or the fights well enough to contribute up to expectations.
