IMO TC is as ignorant as the people going completely against him.
It's all up to preferences. Would you rather take the change to be paired against a pokemon that might be super effective on you or completely useless against you. Or would you simply want to be in mid and not take those chances.
It's all up to preference, not what is "good" or "bad". But obviously some people and especially the TC believe their word is absolute. Hi god.
