Speed up builds idea

Hi, so ok I had an idea about build upgrade times.

obviously the higher a building the longer it takes to build, understandably.
Now I and I guess many people are not willing to spend a thousand or so cristals to instant build, but I would be willing to pay some crystals to add another builder to help the first builder and reduce the build time.

so 8 days to build, add a second builder to the project for 100 crystals say and the build time reduces to 6 days or something, and you could keep adding more builders to it as long as they were available.

let me know what ya all think.

Please read the sticky, this is a ruled out idea
