Personally, I like the kind of magic that exists in Wheel of Time. It's powerful, it taps the fabric of reality itself, but it's also extremely dangerous and you need a lot of practice with it to do anything. People with the talent absolutely [i]need[/i] training, or they'll hurt themselves and/or others, and if you screw something up it'll bite you hard. Not to mention the conundrum it poses with how addictive it is to use, but how easy it becomes to slip up and pull too hard on it if you get too greedy for the feeling it gives you.
