Mists of Deception -- exploit??

[Burnsaber]

Dude, that's a pure exploit. The battle shouldn't continue if there's no-one actually fighting in the other side.

I have had wrathful skies used against me, with the mage that cast it retreating afterward, but with storm up and enough chaff that my my army suffered big damage before it finished off the chaff.

I agree that battlefield enchantments should end when mage is killed or he retreats.
