If I run with GG runners, ZDS is much better.
Can you explain why? If I am running with GG runners, the group is set up properly, does not need a stun monk (CM Wiz) and benefits from the extra (if only slight) dps that a fellow GG geared monk could do.
I can see this benefiting a group that is not GG and does not have a Wiz definitely. This gear set up won't be used on the "fastest" clear times by any means. The skill set up works well for sure.
This is the conclusion I also came up with last night after being bored and building a ZDS set to play around with.
Granted the monk in your party is properly geared and skilled, bringing overall DPS IMO is better then MOH/GL.
For white clearing/exp farming, a proper team will gather large groups instead of smaller groups and deal dmg all at once..With a 2.0+ APS and high CC, they will be easily able to tag 1-2 targets with EP since spirit will be generated much faster when multiple targets are being hit with FOT:Q. Secondly, their CS will actually deals a good amount of dmg since the attacks scales off weapon dmg. Same goes for DS.
For elite clearing only, I guess the same as move could apply. A properly geared monk will be able to tag at least 1 if not 2 of the elites before they are dying. With a GG team, even without EP the elites die in under 12 seconds..
edit: My ZDS monk isn't the greatest as I just picked alot of the cheapest gear I could find to experiment with. I found the sustain to be pretty MEH tbh, even at 900 res,3800 arm, 70k life , 2000ish LOH 2.84/3.08 APS.
