New Building Idea

There needs to be a building whose purpose is to convert one type of resource to another. All to often I have a ton of one resource but need the other. You could call this building the market or something of that nature. There could even be a service charge for using this building or it could be a one and one exchange rate. Just a thought.

But I feel like it would defeat the fact of having mines and collectors. If you could do this you would really only need 1 resource.

Sorry, this is already ruled out...

I dont agree. If you have 6 lvl 11 gold mines and 5 lvl 6 elixer, its unfair to make gold into elixer.
