In all honesty, they are way too powerful at the moment. I'm not sure what the best way to balance them is, but it's more than a little crazy now.
They should not exist on South Island in general. It defeats the purpose of the island. Also, South Island is more of an exception where the capital has close to 100k population. Not many cities in the game has population close to the three cities on South Island.
It is very difficult to deal with them.
I am sure Vita` doesn't want to make them go away but at least for South Island, it really should be removed.
Also, can we please test new features somewhere else before implementing them especially when they are so game breaking as this feature?
