Hey there. I've been multiboxing Diablo 3 since beta. To the best of my knowledge I am the original D3 multiboxer, after Lax of course. I started with Demon Hunters, and switched to Monks after being a part of Inigo Montoya's stream for a while. Follow him as well if you haven't already. (http://www.twitch.tv/d3_inigomontoya) I've wanted to stream for months, but I wanted it to be high quality, so I waited until I upgraded my rig. I've been streaming other games for the past few weeks, and I'm happy with the results.
I'll be playing Diablo 3 tonight, so please stop by and take a look. I'll be giving away every legendary that drops after I hit 20+ subscribed viewers.
