(posted the idea in another thread earlier but this is a better place for it)

I wish the ai would never override my choices of spells to cast for the purpose of saving gems when I am storming an enemy castle. The reason is that a few enemy mages that my big army could easily kill on an open field, are much harder to kill when the castle walls block access. And defensive spells with a gem cost are sometimes very usefull against the arrows from the castle.

The gem-saving ai should still be active for the defender of the castle to prevent it from wasting gems on a single attacking scout.
