http://www.diablofans.com/builds/70863-2-4-super-smash-barb-globe-barb-for-100-speedsthose builds are tanky and feeds the wizard (the dps) health globes so they regen arcane power (reapers wraps)
The last one is probably prefered, since it drops more globes, especially on single target (rift guardian etc)
If u want to pull, then u probably want a monk or perhaps the first WW barb build
However, if u are "only" doing grifts 65, u should just go for max dps
edit:
This season is about buffing the wizard in your group the most
1 Wizard (dps), 1 barb (makes globes for the wizard), 1 WD (much bonus dmg to wizard) and 1 monk (toughness, can do globes and some crowd control)
