Dekai, thank you for the reply! You are another invaluable member of the pyrotech forums that deserves a gold star.
I have also had to spec pyro for DPS in PvE, however I would still like to PvP and the switch is quite dramatic.
I was in a rush in my original post, I should clarify that I am using a build as a semi-fresh 50 (after rerolling my 36 Jugg):

My main focus here is to be able to make healers lives a living hell in PvP, while also remaining strong in PvE content. Did EV 8 man with little difficulty.
Would the endurance in PT help? I think this would be minimal. Also the lowered CD on electro dart might be useful for the long fights that tend to occur when you corner a healer, however at what cost?
I guess I am also wondering if it is viable to remain as 21/2/18 (with CGC) without a significant loss in DPS in PvE content?
As for your suggestion of having healer friends, I have two friends that are low level at the moment who are specd for healing, however the amount of 50's and premade groups of full champion geared players is making it difficult for them to effectively heal me/the team, unfortunately.
Are there any classes a PT should avoid? Obviously running into a group of 3+ enemies cannot happen anymore, either.
