Ideas and suggestions.

If everyone is complaining about the lack of control, why not create an additional way to gain it? And a skill that only works in the final battle doesn't seem very appealing.

By the way, here's another interesting idea (so interesting that I'm not even sure if it's worth adding): the ability to see what spells master genies, fairy dragons, etc. can cast on the adventure map, and the ability to learn one of these spells of your choice.
