Conjuration/restoration mage is awesome.
I have Lydia as follower with me most of the time, always have a conjured minion up, so that I have 2 extra sets of damage plus 2 extra people to help take damage off of me. Then, in my other hand I have a conjured bound sword to throw down damage as well, with high points in restoration to keep myself healed up in case of emergency.
Build is holding up quite well.
