I'm running around in a ZDS build right now. It's a build completly made for supporting other players. Works well in MP10 if you team up with some 170-200k+ dps players.
But since my damage is just over 21k I can't do anything alone. But team up with some good dps and stuff just melts.
The control and damage buffs are pretty awesome in this spec & gear aswell.
He's kinda new, as my Barb, I was a DH/Wiz player and recently went back to D3 and decided to try the other classes! Right now I'm leveling a WD but they are all mostly waiting for RoS to come out, I sold my gems and got 1b for the expansion and around 200m on the AH and some USD from previous transactions I did with the RMAH, but will save them and doubt I'd upgrade him much more with other than some lucky crafts...
