I think I never played something else on my zealot here on the server and that's for like 71 renown ranks and I still like it.
The build really depends on what you want to do.
----For AoE in a zerg you want to go with something like this:

You want to drop your ritual up front into the enemys so that the small dmg procs can fill your AP bar. Then you are basically open to spam any AoE you have. If you get at high rr you can get the aoe kb or the stagger. Stagger is very nice for when you run around alone or stagger a backline healer. For zerg play you often don't want people to be knocked all over but sometimes it can definitly be useful. Go more deffensive in your spec since lots of AoE skills form the zealo have not a high range. You want to hit the enemy lines with Demon Spittle to remove armor for your meeles and resitance for yourself and some skills of the sorcs.
----For ST DPS there are several builds around I run:

with the stagger, cause annilator. There are people running Witchcraft and Dark Rites but I found if my burst is not up par with a sorc I usually bring the AP ritual and the HD which are quite worthy for a group aswell.
I tested MoM after the change for several weeks and these are my finding.
Right now I think my ST dps zealo brings more then a dps shaman however the zealots I saw on few occations happen have serious problems with it and there are good reasons for it.
For good burst you need to keep up several dots on different enemys (2-4) while coordinating your burst with your teammates while looking on your own team HP and switch the deff target accordingly to make the most use out of transference. You should upkeep AP ritual at all times. You should be ready instantly to find a squish enemy and cast BoT to save a teammate. You should be very careful where you stand since you are SQUISHY. You should keep track of which enemy healers are where and how are their immune timers to make sure you are ready to stagger when you start bursting.
I'd say shamans burst however doesn't need several enemys to reach full potential and is a bit quicker pulled off (however zealot burst is nice too even if you don't have ton's of procs because you didn't had time to propperly dot). Shaman is the only heal class I actually play on heal and not dmg so not so sure about that. I'd say shaman can still throw some nice normal heals due to their class mechanic while zealo has to change harbinger to bring any normal healing which therefore locks them out of doing any dmg fo 20s.
I often play my zealo in team comps it works nicely with a 1-3-2 setup but with the current burst of WL you/your healers will have to be even more careful since a WL needs 1-2s to down me. Other dd's are no prob however you I can kite pretty much anything if I'm not getting caught up by a rdm shrub in the landscape.
For roaming great class you can use most your skills while running and the stagger is just outright cruel to someone trying to get away. WH can be annoying if they happen to kill you while staggered but if you have a healer or guard they are no problem at all. Keep away from WL's they are totally able to kill you while you have a healer and often even through guard.
Zealot is a great class for pugs. You miss healers in your team: switch tactics and harbinger and since zealot is kinda special on their skill trees your heals are just as good. I usally pull off higher numbers then most healers in the sc but don't forget your positioning from playing dps zealo since you still will be squish. You have enough healers go to your normal spec and bring some good dmg into the ring.
I'd say AoE zealot for zergs is atm quite viable while st dps zealot currently needs a bit more love either through:
-A ranged resitance debuff (like the old harbinger), I think this is something crucial I find myself being able to crit enemys between 1400 and 700 (both without guard) and while your dps is absolutly okay if not great at low restiance targets but compleatly laughable at high resistance targets.
-Pushing it's support capabilits through a support heal/dmg heal; Comparable to doks benefit to the group. Emergency heal to bring sustain to a group since you lack burst. I could think of making BoT instant since I often have not enough time to get the 2s cast through (even with FM it sometimes is just too slow to react) before someone dies. Reworking MoM to resemble Rend soul (obviously not as stong since you are ranged but being at a state where you can actually save someone)
-More burst obviously however I'd find giving it more burst you kinda loose the supportive role of dps healer
-More sustain you kinda loose the backdraft of a ranger
I sent now but might be editing/correcting a bit on top of it.
