I have always liked to have my upkeep below my food resource production. But with each release of new keeps & new troops that have higher upkeep the incremental increase of resource buildings has done very little to keep up. Sharjur was awesome help but still at 200mil power, qty8 level35 farm buildings & some china subs I'm barely breaking even. With every keep I increased I looked forward to being able to produce more only to get a dismal increase. My suggestion is that the incremental increase for resource production should be much more then what it is considering the investment of time speeds & resources it takes to increase those buildings.
