I don't really buy the whole argument that some people just like to be dicks on the internet. If you're trash on the internet then you're trash in real life. I still can't figure out why MMO's attract such dicks. This is a fantasy game, not the NFL (not that all football fans are dicks).

Side Note on Duty Finder:
I would love to see a tick box you could check that flags you as a newbie to the instance. And then also have a filter that people could use to either not allow newbie, allow only newbies, or a mix of both.
