What kind of magic do you like the most?

But the fact that "neutral magic" lacks any system makes it impossible to compare it with clearly defined Chaos, Darkness, Summoning, and Light.

Really? Are we not allowed to compare a system with a lack of system? And what are we afraid of? Let's compare them. Don't lie and don't be afraid...
Besides this school, there are the school of shouts, the school of spells cast on the map, and the rune school. They are also magical; let's compare them too. What's wrong with that? The rune and shout schools have a clear system.
