Orcs – discussion about the race.

Perhaps the mage doesn't have a powerful ballista or an even more powerful sworn enemy. And he doesn't have an Arcane Wave either, so you don't need to be too afraid of Chaos magic. But it's worth investing in Anti-Magic. Although, of course, it's all a matter of personal preference. You can choose not to upgrade any of the resistances. Just don't complain later that the Sylvan faction has a "cheating" ballista or that Dark magic is "overpowered" against Orcs.
