Still playing my Wizard, coming up on 300 hours played soon (which is nothing).
I love having the money to kind of play around with different gear and builds. I had some +Cold and +Lightening gear and ran with Shock Pulse and Blizzard/Hydra, and did really well in Act3.
These days, I bought +Arcane and more Crit, and I'm doing a Critical Mass/Meteor build, which is insanely fun with some APoC.
