As someone who doesn't want trade in the game it seems like the only question worth answering is the first one. Which doesn't seem right unless you're already leaning towards adding trade back?
I also think there should probably be a question regarding whether people will actually play the game if trade is/is not implemented because the assumption that the poll seems to make is that people that don't want trade will continue to play even if you add it.
As far as feedback is concerned the only way I can see you guys pleasing everyone is if you do two leagues. 1 league which is balanced as the game currently is and 1 league with open trade that has its own separate trade focused balance.
