Controlling the rushed Town Hall trap
Surely everyone see this? Kids, or adults who don't think far ahead, with rushed TH bases, usually achieved by spending gems, controlling an account that they don't have the skill to use. The game is ruined for them, they can't hold their own. They hurt any clan who includes them, which is hard if they are friends or family. This is only really an issue after TH7. Upgrading prematurely once hurts. doing it twice is severe. Three times, (eg TH9 without even dragons) and your account is stuffed.
there are two simple things to prevent foolish premature TH upgrades:
1. Make the TH cost a whole lot more, maybe as much as max storage of gold, elixir and DE. (In the scheme of things, this cost is inconsequential). Currently, TH upgrading is cheaper than other upgrades individually, and collectively is much much cheaper.
2. Create a goblin single level base that must be defeated before allowing the Next TH upgrade. This will require the player to have some level of skill.
Neither change would prevent someone from rushing their TH if they know what they are doing.
