A full-on freeday is not jb in any way; a freeday is the absence of orders. If a whole round was just a freeday then the CTs are being plain lazy.
If a freeday was to be called part-way through a round I would always revoke it so that the other CTs have time to get ready - if the Ts get to go anywhere while the CTs aren't prepared then the whole team would be essentially screwed. If someone wanted to call a freeday midway through a round, I would not revoke it if they gave a time to prepare or warned the team beforehand; however if the freeday is called only 1 minute in then it would always be revoked.
I co-operate with my teammates if they give actual orders, not freedays - you know this from watching me play.
