For the case of Terran vs. the Zuma simply get a statement from each player in Terran that have been there for at least a year about how the feel the Zuma have been affecting the game for them and why.
Why don't you ask them all to come here and state their opinion? If you can get each player of Terran to come here and state their case, then I think you will have a much stronger argument than "It was completely ridiculous and retarded."
