Spend gems to speed up construction and upgrades
I was thinking that if it was possible to spend some gems to increase the construction rate for few hours.
Since not everyone of us can pay money to buy loads gems to complete an upgrade/construction but we could use those gems collected by achievements and clearing obstacles to boost construction of buildings.
It should require town hall lvl 8 or maybe lvl 7 to unlock this feature to avoid negative usage.
Thank you for reading
Please comment if its any good or worthless.
