Good luck Xzin, although personally I wouldn't be caught dead on that show. He's made his point of view clear, and I assume you know that it's going to be a debate, but if it were me I'd say "Why should I argue with this guy, he's attacking my play style to get attention." He makes his intentions clear right in this line: "But I, Mike Schramm, personally have always been quite against the idea of multiboxing." He only has one thing in mind: making a name for himself. I got a distinct Michael Moore vibe from him. (My apologies for referencing politics, but even most of M.M.'s supporters will admit he has some level of personal gain in mind when creating his documentaries.)
Plus, am I the only one that laughed about the part about his coworker coming on the show two, who has "actually multiboxed two characters at a time." I bet he had two computers and just hit some buttons on his second keyboard to control, nowhere near the type of complexity as most people in this community deal with. I could be wrong, but still would be very surprised to hear this Adam Holisky guy say "Yeah, I use Keyclone."
All that being said, my proverbial rainbow after the thunderstorm is the fact that Xzin will be there, who I consider perfectly able to speak as my representative. Good luck Xzin!
