Alright ... I did it!
I spent most of this weekend playing zDPS and perfecting my gear.

I made some changes from what I started with (a near mirror of Vox's setup) due to playstyle choices.
Specifically, I HATE FoT-Q with this spec. I spend so much time spamming skills that I rarely make it to my 3rd combo hit even with 3.0 APS so I made the switch to CW-RT as my only generator.
I also prefer the route of STI over OWE. This mostly stems from having some pretty amazing Dex items already and being in Phys-res which makes OWE much less appealing.
Here are some of my results from me weekend of zDPS fun --
1. I gained something like 40 paragon levels. I have no idea what my overall xp/hr was, but I am at like 10 hours played on my monk and she is para 43 already...
2. zDPS felt better than every single form of actual DPS I could come up with. It isn't really hard for me to live using a single LS wep and a buff-monk setup with my DPS gear at ~250k. However, even with SW-C it felt like I was doing almost no damage compared to the Archons, Bats, SNS and Barbs that were WRECKING things in my groups.
3. I finally had the absolute pleasure to run double-zDPS + 2x DPS with Vox and I can confirm that it is pretty nuts. We actually killed things FASTER because with 2x zDPS you can focus a little less on CS and a little more on EP while the other guy does the same. This results in upward of 6 EP's per monk per pack and that really adds up.
4. It's ... so ... fun. I don't even know how to explain it properly but one of my big problems with grouping was always that the things you did were SO specialized. When I solo I have to account for my own eHP DPS grouping movement ect ... when I grouped it was just: stand around and wait for the movement person to get there then use all your DPS buffs and spam your one DPS skill for max value.
zDPS does NOT feel this way. The massive APM's caused by such high attack speed and the constant positioning requirement combined with dropping the safety-net that is LS made for some seriously interesting gameplay. Plus, the new "fotm" DC run requires multiple phases that can all by optimized which is nice for variety's sake.
All in all, just when I was starting to run out of things to do, this spec has opened up at least another 100 paragon levels worth of fun for me! :D
