Supporting armies

[Perdi]

I should be able to send troops to one of my cities and have them become part of that city. That way can attack from any of my own cities

You might want to do a search as this idea comes up often. It sounds great on the surface, but there are a lot of really, really big negatives associated with it.

I agree, a much needed feature is the ability to let the other city "control" your supporting troops, but yet retain the ability to override their orders.
