Which style in the left hand is the most effective - a shield, a spell, or a second weapon?
In particular, I'm currently playing a heavy-armor mace-wielding orc. From the little I've tried of dual wielding, it doesn't seem particularly effective - the inability to block makes you seriously fragile... but it look so cool. Is it a build that becomes more effective as I invest in the dual-wielding perks? A shield fits nicely with the Orc Juggernaut archetype, but is kind of boring.
