It would be very cool, and efficient, if I were able to select what kind of spells my mage is allowed to cast. It would work as a list of binary YES/NO switches. All spells are allowed by default.
The categories could be:

Area effect offensive spells and Spells Which Can Harm Your Army - to disallow casting Breath of Winter and suchlike.
Direct offensive magic(precision-dependant offensive spells?) - to disable fireballs, firedarts, flying shards, and all these annoying spells which usually have hardly any effect. They're especially pitiful on Scorpion King pretender (precision:9). As it is, fire magic on a pretender seems a disadvantage, because he keeps wasting time casting silly ineffective spells.
self-buffs - personal luck, twist fate, and so on. These are good on SC's, but there are ocassions when you don't want your mages to cast them. On the other hand, SCs may want to disable all else.
Team buff spells - all kinds of spells which target multiple units you control. There are reasons not to use them - high fatigue cost, etc. Sometimes you attack with a small group of commanders, and +3 armor isn't really going to do much.
non-combat combat spells - I mean stuff like Horror Mark, Curse, Seven Years Fever.... They're ok if your commanders are going down and will die anyway, but not in a serious battle I think. Well, curse may be useful, but not others I listed.
summonings - to have more options.
spells with gem cost/fatigue>100 - for fighting weaklings with well-equipped mages. I know one alternative:transfer gems to another commander.

Spells would have to be manually inserted into each category (by game developers). Comments ?
