Chamnix brought up in the ruleset discussion thread one possible change he'd like to see: moving map trading up to Map Making/Astronomy/some required tech. It is a very valid point, so, I created this thread in case there are other changes you would like to see be made, and then we can create a multiple choice poll for the teams to vote on them. Maybe you want communications trading to go back to Writing, or something like that. Suggest them here.
