The Speed Of Building(Idea)
I assume not everyone is very enthusiastic about how long thing take to build once you get into a higher rank or your build require a longer time. My idea is regarding builders and how while you make one builder build a single defense or what have you while the other ones sleep. I feel it would make the game more efficient or have the player more enthusiastic about playing the game if the builders who are not working on a build could help the main builder of a defense upgrade,etc. so that the time for that item to be built or upgrade takes a shorter amount of time.
Now, if the player wishes to be building or upgrade three things at once(if they only had three builder), the time it would take would be the usual it is now but when one of the builders finishes their build and becomes free, it goes to help the other ones build what they are building. Its a simple concept, hope you guys consider it so people use strategy if they want to at least a little quicker build something or build things only using one builder.
