Wrathfull skies or any other spell don't allow the defender to always win if his mage survive, I think the difference is there. There is nothing to counter MoD once the mage has left the battlefield.

It's also very easy to abuse the 5 rounds rule, i.e using militias or other weak expandable troop with low morale, going to rout in round 2 or 3 (and storm to avoid fliers).
