Why were these changes even considered in the first place? I don't recall anyone being upset about army or resource trading. It's entirely optional and, if done improperly, can screw up the participants far more than anyone uninvolved. The realism excuse doesn't make any sense in this context because, unsurprisingly, nations traded with other nations outside of their own alliances. Additionally, there were plenty of examples of troops from other nations being placed under the command of a different nation.
Please revert these changes, they don't add anything to the game; rather, they actually remove from the game by making roleplay rounds nearly impossible to setup. It is already hard enough to get players together, coordinate with eachother, set house rules, and have things run smoothly in an RP match - it's even harder when the game's mechanics actively discourage it.
Or, give us the option and allow us to set up non-ranked, no reward RP matches with custom rules and nations.
