Well it kinda depends on where you decide to party though Crevox.
Before they added map#2 zones you needed quite a strict and demanding pt setup if you wanted to CP in Woh Gates (map1) to name an example.
Woh Gates map2 Bats camp is awesome exactely for that reason. There are no debuffs, there are no dangerous TP moves, anybody can heal. I managed to mainheal on SMN/RDM, on BRD/WHM, on GEO/RDM and many other jobs.
On WHM it was utterly boring and on SCH it was Regen5-ga then afk for 5 mins.
PT setup there can be extremely varying, keeping in mind that without a buffer you won't be able to reach top speed, but it would still be decent.
For other camps you kinda need a real healer though.
Take Sih Gates. The Bats+Diremites camp is awesome, but there are annoying TP moves to debuff there, and Diremites use a Slow that overwrites your Haste, making it an annoying race of erasing and recasting etc.
All other camps in map2 are like that. Either there are mobs with annoying/dangerous TP moves, or annoying stuff to -na etc.
Not saying they're not viable, they are, but you gotta be a bit more strict with the setups there (altough you still have a high degree of freedom).
My main point, as I've said elsewhere already, is that the bats camp is so good, so good, soooooo good that it kinda spoils people, and the other viable camps, as good as they are, will never look as good as the bats one.
That's why I said game could use a couple more nice camps like that one.
And the "more annoyng" camps should reward players with a slightly higher cp x kill, I think.
That would be a good way to balance things up I guess.
Anyway, the way things are going (with JPs being more and more useful/necessary, more JP categories being added etc) they really need to do something serious about the cp/hr gain thing. Emphasis on "serious", and no, the annoying CP cape or the trolling of CP+ through gift is not a "serious" way to address the issue :P
