I started dual boxing the other day with the RAF feature, and so far it hasn't been too bad for me. I had one guy stop and chat with me about it, and another person go "WTF? Why two accounts?" My favorite thing by far though is when someone just stops, and turns to watch you go by. I couldn't imagine what it'd be like if I had 5 going at once...

Two things I don't get about it though (with dual boxing) are:

1) Why couldn't it be me and a friend playing together?

2) I'm leveling way, way faster than they are, so I actually play less then they do, yet I'm the stupid one. *shrugs* (This would be especially true if I could 5 box, which means I could run instances by myself, and not have to wait for groups...that's the dream for me...)

I still enjoy the screenshots though.
