Marketplace - Resource exchange

I often find myself with 900k cement, while 400k steel. Sometimes I have more of one resource than another, and they max to the limit and i can not do anything to lower them untill im done building/training ect.
I suggest a marketplace where you can trade certian resources, either through AI or other players with a 3:1 ratio.

If I want 500 steel, I could exchange it for 1500 cement or food.

Anything with cash is a 4/5:1 ratio.

500 Steel for 2000-2500 cash.

That way you will lose profit, but you can prevent maxing out resources and not being able to lose efficent progress.

I would use this marketplace only under circumstances where.. If my max limit for all resources was 100,000.. and I had the following..
100,000 steel
35,000 food
85,000 cement

I would exchange about 30,000 steel for food, adding 10,000 food leaving room for all of my resources to efficently gain again.

Well thats about it, thanks for reading.

Well it makes sense, specially when it comes to training units as some of them usually have a certain resource that requires 3~4x more than the others, as such im on 500k cement and iron, 3kk gold and 130k food and the food rate is pretty much equaled to other resources.

i agree
