And that you might not always get the piece when it drops. Its not as if me and my teammate will always have the pieces that the other needs. We will have to roll. In which case it would be better on my own as I could kill the entire area just as fast on my own.
The socializing argument is odd, but I agree. I've teamed up with people killing mechdogs, but I never made long term AO friends from it. I could team with someone and chat, but we would also chat about how annoying the farm was. It still took almost 30 minutes to farm, thats plenty of time for socializing.
