I am playing my wizard and monk too. I set my barb aside for a while until I think of a good dual wield build, since blizzard broke spin to win.
For the wiz I decided to go with a fire build, and it's currently my fastest farmer, I can do t1-t2 no problem
This is the build: http://us.battle.net/d3/en/calculator/wizard#bPiSjO!YeT!ZcbYac
Basically you buff up, spam fire pulse 5 times to charge arcane dynamo, pop the hydra, spam again 5 times, nuke them with a meteor that crits for 3.5M damage. keep spamming, rinse and repeat.
For the monk I am using something similar to what I used pre-2.0, but with the changes and some skill switching, it's much more effective now, but still a little bit slower than my wizard.
Since everyone uses dual wield or wep+shield monk, I decided I should go for a 2H burst damage build (rolling with a Skorn). It's a bit fragile but it's fun and works perfectly in T1, for t2-t3 is a bit slow still, but I also need better gear.
