Wish List: targetable spells

[Endoperez]

Oh the joy! This is better than what I dared to dream! Anyways, some questions for you about the mage AI:

IF a mage has skill in multiple paths, how does he decide what to spells to use? Does the fatique the spell causes taken into account? What about storm/ rain and their effects on the fire magic?
If the mage has gems and no (intelligent) orders, does he summon or does he cast? From what this depends?
Is there any situation in which the mage casts a wrong spell more often than not?

The Last one interests me most. Does the AI have any faults? And will the players be able to use them? Like getting the mages to use the gems with Call of the wind...
