Yeah, most of us have been playing long enough that the whole, "Go do 5-mans to L2P." is kinda moot. I think anyone in this thread is already beyond that point. As for "improving your character" I thought we just had the discussion on stats. Besides, remember we're talking about 5-man starter dungeons for pete's sake, exactly how "perfect" do you expect everyone's gear to be?
Not to mention that if you are serious about improving your character, might as well do 5mans to learn more about the job you intent to do. If you're not caring about improving your char then 1) It's pointless to talk about gear upgrades and 2) GTFO of my group, I hate slackers!!
