Many people want Healer, Dragon and other awesome troops. I have an idea of hiring troops for a limited period of time example if you want to hire Dragon for 1 week you need to pay XXX-Gems, after hiring troop(exragon) you will unlock Dragon in barracks for one week, after one week it will be locked. I think this idea is good for SUPERCELL and also for every player.

Hope you like this idea, please tell me what do you think about this.
