Everyone doesn't buy gems, like me and that makes it very expensive to complete an upgrade. But if you could boost your builder to build 2,3,4 or 5 times it would be a lot easier. I know it is downsides to this, for example gems will loose it's worth because you can boost instead of just pay a 1000 to make an building done building. But if you could make an cool down a cost of 100 to boost it would be nice..
just an idea, my third in two days:cool:
