I know each game is different, but I think my favourite mage type would be Red. Why? Because while they can't hurt as much as a Black Mage or support as good as a White Mage, most games allow them to use harder-hitting weapons. That means you don't have to waste MP as often, and in some games that's critical.

If we're talking about my Favourite Mage, as in the person, I'll go with Ultimecia, but that's off topic :semicolonpee:
