No no. A Battlemage, for me anyway, is a proficient Mage user who wears heavy armor and uses heavy weapons. You can't call Ocato the Imperial Battlemage, becuase he's simply a Mage, by appearance anyway. :shrug:
Oh, I see. I totally misunderstood your post then. Thouh it was about mages not wearing robes = not mages.
But now I agree, that is what a battlemage should look like. But Ocato is not a common battlemage, he is
the Imperial Battlemage, and in Oblivion (edit: as he appeared, of course), he is also a politician. Politicians don't walk around wearing heavy armour and war hammers, do they? :foodndrink:
