I have upgraded everything in the first tier but it feels like there is not much value for the upgrades unless the belt speeds up as well. I feel that adding an increase to the belt speed in the first tier would make things a little more interesting. This would allow me to go back and compress my current builds. Just a thought. The only value i found in the first tier were the budling cranes and the ability to upgrade my building.

You mean in rank 1 you would like to have access to the faster conveyors already?

i would place it somewhere in they grey upgrades. maybe after the building upgrades. I just feel that most of the current upgrades do not add enough benefit to merit change in the builds
