I'm leaning towards either a Altmer spellsword, Nord shouty character (assuming there's a shouty class), or some kind of 'leader' class. The Captain class in LOTRO has been my favourite MMO class by far - he's a strong buffer, can off-heal, has some handy debuffs, and can still hold his own in a melee fight (another friend I met through my guild playing a Captain and I blitzed through many of the duo quests )
