Put those builders to work
My idea in a nut shell is to keep all the buidlers working by allowing an upgrade to be built on by more than one builder. The assistance from another builder wouldn't even need to match second for second. Essentially as one builder finished their upgrade they then would go and start helping the next builder who is closest to being finished. I personally think this would allow for more strategy for the players. It may seem like I'm referring to the boost feature of the new world in a way. I'm not. If done at a ratio, with all five builders working on one upgrade the total gain would be one second. Two builders would clock 1.25 seconds, three builders at 1.5 seconds and so forth. So this gives players a unique option for strategy. If possible allow players the to choose where their builders build to allow players to have three builders on one upgrade and two builders on another. Now with the new world it would be cool if builders could travel there.
