Thanks for the tips. I've been having fun lately with the Vorcha Soldier, and it's a little easier to pick a good build there - I just skipped Carnage and went with the Acolyte/Flamer build with a light backup weapon. He's pretty survivable with maxed Bloodlust and fitness. I was thinking I'd want to max fitness on the Sentinel too but I'll try out the 66653 build. Maybe Instead of a Power Amp I could throw on Cyclonics.
Thats a waste of cyclonic- his base shields are pathetic, you get virtually no mileage out of one (Cyclonic IV is +325 shields... awesome). If you feel nervous about survivability, trade that 15% power damage rank 5 passive for rank 4 of Fitness, and consider the speed/melee evo of Bloodlust. You won't really notice it anyways, especially if you end up using a power amp (which is a good idea- either that or adrenaline are sort of the only reasonable options anyways).
And obviously the Acolyte makes alot of sense from a min/max perspective, but consider using something a little more fun and Vorcha-ey, like a shotgun with Disruptor rounds (disruptor makes it a good anti-shield gun, and now you're setting off TBs as well as FEs)- my favorites on him are Venom and Raider.
Oh, and I'M ALIVE!!!
