Counter to "Fog Warriors"?

Earthquake is good, but more than 1 is better, if I am playing a nation with high hp troops (preferably with regeneration), I love casting earthquake 3 times in the same round. It eliminates all enemy mages, archers and other chaff. Your high hp regenerating troops can then finish the shell shocked remenants with ease.

If you have 3 lvl 4E mages, give them 3 earth gems each and just script Earthquake, hold/castspell, h/cs, h/cs, h/cs, stay behind troops. This could hopefully eliminate any enemy mages before they even cast fog warriors.
