As linked above, this conversation has played out over the past couple of years. The consistent feedback we get is that people don't value open-ended "rate my in-game team" posts. We can't please everybody, but we have tried to keep in-game team advice that is likely to be reused, via rule 1.6.
I want to comment that if we did allow "rate my in-game team" posts (in a new section or otherwise), it may not take the form that you expect. The focus would be on optimising the team for the game in question -- potentially to the exclusion of team members that the author is attached to. I think most people choose mons for their in-game team because they like them, not necessarily because they are the most efficient: and therein lies the biggest obstacle to having a feedback-driven section for in-game teams. Even our "igtq" threads attract people who just think their team is cool and want to share it.
