Well written and fun guide. This is also why it pays to train yourself to instantly forget chat after reading it, if needed, to keep your cool.
Personally, I'm going to work on having that "super tight" game and getting as immune to taunting as possible, rather than working on my smack talk. But I can definitely see it's usefulness in turning the tide.
