I played the first game as a Mage and used a bow for a long time in the game.
The second game I played as a warrior, after I got the stats (strengths, agility) to use better weapons (singing blade, balde of chaos) I was just unstopable.
IMO the warrior was easier, the lack of mana you have with the warrior can be overcome with some charms and you find tons of potions to fill up mana during the fights
