Please tell me how this works out if you use it for pvp, I have been curious about making a build like this, although high damage magicka abilities are limited, you could use dark deal to keep your stamina up for charges and dodge rolls.
In the previous patch I often ran 2h/resto stam build but now I have since shifted my thoughts on this.
But for a mag focus this is probably what I would run for skills

edit; should be elemental weapon
leaving gear ambiguous so I don't give away too much about what I run.]
