[BB idea] The Clone Tower

First, this change is as insane as removal of training time. It is extremely unlikely that Supercell adds this, but it addresses a critical flaw with Builder Base: It gets pushed over by Home Base. Second, ask yourself if you would have uninstalled if gems, CWL medals, and Raid Medals didn't exist, and you'll quickly understand how big the flaw of having to choose which base to spend premium resources in.

The Clone Tower (available at BH5) will duplicate premium resources to only work in the Builder Base. This will be CWL medals, Gems, and Raid Medals. Each level will make cloning more efficient (so at level 1 every 100 CWL medals you get, 10 CWL medals are appointed to the builder base, and each level will increase the CWL medals you get by 10 in this example). Any Magic Item bought with cloned resources will also work exclusively in the Builder Base.

The Clone Tower, besides making the 6th Builder easier to get the more CWL medals you receive, will actually allow to engage in the most important aspect of playing Clash of Clans: Speeding up your base progress. It is currently not possible to do so because it hinders your time to max your Home Base, which is the only important base.

This addition will make maxing the Builder Base a bit too fast, so I expect at minimum the addition 3 more "Town Hall" levels for the Builder Hall.
