I know dual wield is really a huge boost for Templars -- not just because melee increases your magicka damage more than ranged, but also because you get another set item slot. But I was thinking about how one of the destruction staff passives boosts the damage of AOE attacks if it's a lightning staff, and how the Templar's bread and butter spam attack is basically a limited AOE attack. I was wondering if that bonus could close the gap, damage wise... because if so, the heavy attack of a lightning staff is a lot easier to use to get magicka back, and once they take magician out of the champion points thing, getting magicka back is going to be something everyone pays more attention to.
What are your thoughts? Is there an advantage/synergy to lightning staff that makes it a viable alternative to dual wield?
