MoV usage

[sum1lost]

Thing is, MoV is just as efficient as big battlefield spells for many nations. Fire gems don't have a huge number of battlefield spell uses (fire storm, flame storm, and living fire are the only 3 I can think of), all of which require high fire paths and very high research. Medallion of vengeance doesn't cost anymore, and while it will often deal less damage, does NOT commit a high level fire mage (which you might not even have, for most nations).
