I love destruction, especially the shock and lightning spells, but they can only be increased by 50% using the Augment perks, or more if you guzzle potions.
One of the best spells is Lightning Storm, the master shock spell. Your stuck in place when casting and can get distracted by attacks, but once you fire up you can re-aim your powerful lightning bolt and wave it across your enemy lines doing continuous damage. Helps if you get destruction enchantments to reduce the cost though.
What I was meant to say is 'Yes' but you might need something to back it up against higher level opponents.
