So I started a second character because I enjoy all kinds of different ones.

I wanted to do a battle mage, but now after looking at the perks it looks like pure casters (using both hands) get some awesome perks. Any suggestions? Maybe a third character later on?

I'm just a pure destruction mage, wielding a sword occasionally and use Alteration/Restoration spells.
(Awesome fire spell damage or mix with lightning/frost and heal yourself while casting light in dark cornors, while raising your armor like mad + Slashing like a pro)
