The new recent change that razing Barbarian towns has no penalty and razing independent towns for half penalty does not make sense to me. Independent towns are usually placed in much better locations, so why be able to raze them so easily? As for barbarians, the only time they have a town is either the same reasons as independents, or they take it from someone. What if a barbarian took an AI town? It would allow the human player to run in, burn it to the ground before they get it back, and all for no penalty.
