Which school of magic do you prefer and why?

I like Air for its speed, lightning, flight, dimension door, and Water for its healing, bless, prayer, dispel, clone, and teleport – removing obstacles is also very useful. Earth is also good with its slowing effect, shield, stone skin, earthquake, force field, meteor shower, and, of course, explosion. But I don't like Fire. I only use it when playing as Xyron from Inferno; otherwise, it's useless. The only useful spell is Bloodlust; everything else has equivalents in other schools of magic. And instead of the aforementioned fire wall, a force field is better – no one can pass through it, while many creatures simply ignore the wall. P.S. Author, are you sure there isn't a similar topic already?
