Running a HW with BTSU for a wizard build? Dude, wut? You can make a much more viable build without using either of these items/sets and you'll receive a whole helluva alot more damage/haste as well without them. Gear sets are still not even close to something like Tactician, Striker, Nomad, Reclaimer, Pred from Div1.
For that build, it's not about running optimally. It's about wielding the powers of fire and lightning.
I can have other builds for when the going gets tough, but the wizard comes out when the Raiders are asleep.
