I've had a lot of success with a Dunmer Sorcerer using 2 swords & heavy armor, I basically invested heavily into Daedric summoning & Dual Wield. Running around with 2 pets, 2 swords & heavy armor, throwing out the Daerdric DOT, & smacking the crap out of everything I meet while wearing a Lightning Shield has worked quite well. Not squishy at all, my Ultimate for bosses is the Lightning Atronach, and most recently I levelled Resto staff a bit for a quick heal (swap into second skill line) in case of emergency (which is rare). Often while questing I see many other characters hanging back & not attacking multiple mods dude to being unable to handle adds. Twilight pet will usually pull one add off & my initial attack kills the first mob within 2 maybe 3 hits. I also can pull power from both pools (stamina & magicka) and never full drain either.
