Against light troops(who often have shields) i would say go with magma eruption until your mage has pretty high precision. You can quite regularly hit 10-12 light units per casting with a very high kill rate against their light armour. The biggest bonus is that any unit in the target squares are automatically hit where-as bladewind can be fairly easily stopped(and dosnt kill as many). Against lightly armoured(8 prot or less i would say) enemies who lack shields bladewind would probably be better. Bladewind also scales its effectiveness well with the casters precision.
