My biggest beef with gearscore is the fact that the numbers that they are requesting are getting way too high too fast. I've seen ppl in trade asking for a 5.4k GS to get into ToC 10... IMO the highest they should be asking for is the max you could have gotten in the raid one tier below, i.e. to get into ICC 10 you should be in full ToC 10 gear.

It's a necessary evil, and the best bet is to keep trying, find a pug willing to take you, get your achievement, get lucky on some rolls, and once you get that, you're in like Flynn.
