Dragon Age is much harder if you start as a Rogue because you won't have any of the serious benefits of either Rogue tree at first. I never played a Mage, but Warrior is far more capable early game than Rogue. It will both sponge and deal a lot more damage. All Rogue has to it's name early is a short, no-damage stun.

I would not recommend a Rogue start until you are more familiar with the game.
