Besides, how do you intend to discuss AND Poll and put into instructions, the civic changes, Mercantilism and Vassalage, or is this just a sort of diversionary tactic to avoid vassalage altogether ?
You need to contribute to discussions now, even though we do not have the exact figures.
Getting Vassalage with Mercantilism will net us money and useful troops. I can put a hold on unit production when we reach 16 unit upkeep, now, with the 2 units being made and 4 more catapults.
Easy -- the discussion starts when the next full play session ends. We make the decision then knowing what the situation is then, leaving enough time for the decision before the following play session.
