As has been mentioned time and time and time again, its fine against pugs but any zerg with proper condi conversion will effectivly nullify condi application. Best case scenario is using it as a flanker but IMO there are better classes with condi for that. In comparison power DH is one of the highest dps in a zerg - if not the highest, I've seen 1 DH having more damage in a fight than 5 revs combined - and it amaze me its not meta. Maybe thats a good thing.
Anyway, the short answer is try it out for yourself. Even if you fail at zerging, you can try roaming. If you invest in ascended, you can move most of the gear to a roaming rev too.
