To reply to my own post. I remember a long time ago in xi I had an exp party. Back then, you had a tank, healer, rdm blm and usually 2 random DD. Our tank, a nin , wasn't doing so great. He was trying, he had bad gear, he was asking for help in the party. A member of my group laughed, called him a nub, and said lets kick him and find a good player. The party leader kicked him. I also left the party, telling them all how rude I thought they were, and adding them to my blist so I hope never to party with them again.

I personally believe you would see more behavior like this in DF, and less people standing up to it.
