Multiple workers

I think they should make it so you can use multiple workers to cut down upgrade time

For example

if a gold mine takes 1 day to upgrade with one worker, if you apply another worker it should half the time to 12hr

First this is in the wrong sub forum. Second this idea has been ruled out, please look at the sticky on the first page under the Idea sub forum.

Sadly Supercell has ruled this feature out
