I just had this idea that instead of us only using 1 builder out of 5, you can use all 5 builders on one structure at 5 times the speed with no gem cost. It would make sense. For example if you only have 1 more cannon to upgrade to lvl 11, instead of just using one of the builder's hut you earned (or bought) you could use all of your builder's huts to work on that single structure.
