Maybe something like this...

1x CC/DPS Wizard with Slow Time (dedicated hat is missing from this update of DIII planner) : http://ptr.d3planner.com/922961978
2x DPS Wizards : http://ptr.d3planner.com/475404513
1x Buff/DPS Witch Doctor : http://ptr.d3planner.com/428092216

This is pretty much the same as my current team, just with massive damage reduction and massive damage increase.
