I think there should be changes made to the builders. I think builders should have "skill" points which can be upgraded with gems. Each skill point reduces build time by 1%, with a maximum of 100 skill points. The upgrades would be like hero upgrades but with gems. The upgrade prices for all builders would start at 10 gems, and increase by 5 gems each time. Each skill level would decrease build time by 1%. You would also be able to give your builders names to differentiate them from each other so they can have separate skill upgrades and projects. By default they would be named Builder 1, Builder 2, Builder 3, Builder 4 and Builder 5. When you go to upgrade a building it gives you a new upgrade interface where you can select which builder to use. The builder's skill level will be displayed beside him on the menu. Builders that are currently doing something else will be greyed out. Once you select a builder it will update the build time depending on the builder's skill level. You could select multiple builders and the time would update accordingly. To identify which builders are selected, there could be a check box beside their names. I really would like this to be implemented because as I get into the later town hall levels I find myself waiting for ages to get a really critical upgrade done because they may take many days depending on what you upgrade. Thanks!
