I've tried a couple...the onebar mage one lasted ok until I got to run around in the lava...I make it to the three mages that shoot at you and never had time to apply any defense.
The hardened ward change in particular is a huge boost to the sorc heavy attack build.Option 2: Hardened Ward, Hurricane, Surge, Wall of Elements, Caltrops, Atro(Meteor)
In option 2, you can flex the ultimate to almost anything imo. Atro works for a quick max health boost based on the updated passive, but if you want consistent stats, Meteor, or even dawnbreaker will work. Hardened is a good heal if you don't want to run pets.
