I think that around level 30-50 the Caster class should be able to fly around for a limited time at the cost of huge amounts of mana. If they run out of mana while they're flying, they won't be able to fly again until their mana bar is full, and they take fall damage upon landing if they're still in the air when their mana runs out.
Fly speed is limited to 1/4 the regular flight speed in vanilla Minecraft, so it isn't so easy to use flying as a way to get out of PVP.
