I've always preferred an unarmed assassin over a warrior, but having two warriors doesn't sound bad at all. Might try to play the game with only two warriors some day.

I tried a mage when I first played the lite version of the game and I gotta say I wasn't impressed at all. All the mana hassle with casters and stuff. Used him mainly as a boss backup, hardly lifting a finger when I met regular monsters.
After playing the game through a few times I noticed that mage gets some fantastic gear. Almost makes me want to play an all mage party.
Back to off-topicness:
Those old C64 and early PC RPG's would really fit wonderfully for iDevice. They've already remade Myst, Simon the Sorcerer, Beneath a Steel Sky and Monkey Islands (all of them a tad bit newer games that what we'd want) so it shouldn't be tough to do others as well.
I guess the RPG games don't sell that well nowadays, especially those more strategic turn-based ones. Of course all the action RPG's like Zenonia and Dungeon Hunter sell, but I'd hardly call them real RPG's.
