Fires from afar costs 10F gems which means its not really a fantastically good use of resources, its probably abit overpriced, especially in MP. Personally I would be very happy to see a opponent 'wasting' 10F gems a turn or more casting fires from afar.

Fires from afar is only overpriced if you are using it to try and kill troops. The much better use is to kill commanders, particularly weak commanders - aka researchers. If an enemy player finds your research center and starts blowing up your researchers with this spell you will think its a bargain at 10gems.
