Alright, so, I think it would be nice if supercell added a new trap. This trap would be similar to the skeleton trap exept instead of skeletons, it would realease builders that would have 25 health a peice and slowly repair nearby buildings. I think the rate of repair should be realative to the building they are repairing's health. Like 5% of total building hp healed per second... Or something like that. These traps could cost 500 gems a peice or something if supercell wanted more money, or they could make them cost gold elixir, dark... Anything works really. And maybe instead activating when enemies are nearby, make them activate when a nearby building takes damage. Just a thought, thanks for considering this.
