Clash of Clans is a game of war strategies, but the ultimate goal is to govern the strongest village of all, and for this we need a lot of resources, in which we will spend hours and hours, but those resources will be useless if we do not have a few available builders, since constructions usually take forever and a builder is used for each element to improve or build from scratch...
Maximum number of constructors in Clash of Clans
Until the last update it is available to get up to 6 builders, which is extremely difficult.
This is one of the bottlenecks in the game, as the lack of builders and the long periods it takes to build and upgrade make players desperate and turn to magical solutions like universal books, builder's hammers, gems, etc. .
