Thanks for the insight gents, I kind of like the idea of going with Cull. I am no swtor expert but I believe internal damage bipasses armor. Which would help overcome some of the limitations of not having acid blade from concealment. I liked the idea of lethality but disliked that it didn't have a TA generating ability in the tree, limits your TA to being primarily from Skiv which has a CD. So the goal is to be primarily dps with some healing, not focusing as much on burst of course, but applying alot of pressure. Kolto Probe will help generate the TA for Cull, which will be my hard hitting talent. Will be interesting to see if its as viable in pvp as other builds, depending on my guilds needs I may run with the healing build that Crocolisk linked however.
