Some thoughts/feedback about playing on the same team (GS)

Me and two friends have been playing GS via both cloud and normal multiplayer since it came out and it's really great. We're always playing in the same team and we've encountered two situations/issues and I'd like to check if you guys agree

1. When a player is suzerain of a city state then that players allies cannot enter the city states territory. I find this quite rediculous, if a player is suzerain of a city state then surely that city state should open its borders to the players allies as well? I mean we're all on the same side here and we're talking big wars, life and death etc. This has lead to the quite strange situation of one player having a clear road to invade an enemy through a city state but the other two of us having to go a long way around that city state.
2. When a player is targeted for an emergency because that player has taken a city then the allies of that player cannot vote at all, so the allies get no say in voting down the emergency. Surely the targets allies should be able to spend their hard earned diplomatic favor to convince the rest of the world to not declare the emergency?
3. A unit is currently not allowed to walk through an allied city that has a unit in it, resulting in them instead having to move beside the city through rough terrain instead of using the road network, often causing several turns delay
