I'll evaluate cards on arguments where there's genuine clash on the merits to determine the relative strengths of each argument, and see how well the cards support those arguments. I don't require full cites, but along the same lines as above, the better the cite, the stronger the argument. 5nk Speed's fine, comprehension is the thing. These two aren't necessarily exclusive. I may miss things here and there.
Tag team is fine.
As long as you're not particularly annoying, mannerisms are irrelevant-, I base speaker points on the clarity and intelligence of what you say, not how you tap your feet.
