I would like to have an option for Open borders independent of Non-Aggression. Also Please consider to be able to enter allied cities. I know it was said that the AI will use the environment and build cities to block the players access, but it would make an Alliance more meaningful especially when i cant support my Ally because i am blocked off by his cities. A teleport Ally spell would also be nice. (make it cost more than 5 mana)
