I just got mine to 32, and I've taken every power in the set. I feel like i've read a bunch of posts of people not being stoked about Poison or this combo, but I love it. I slotted all my primaries up pretty heavy so far and basically just ACC in the guns, utilizing the secondary effects for debuffing ATM.
Ank pretty much said it but ill add...
...that I have the heal and it's come in handy about a jillion times already. I have 1 Rech and 2 Heals in it currently.
...Antidote is great Mez Protec with the added bonus of Resist to some tougher Dam types, Toxic and Cold I think. I Rech and 1 DamRes ATM although that is a bit overkill with Hasten and i'll prolly spec out.
...The Rez. It's a rez. I regretted taking it at first and then needed it literally 5 times on the next mish. 1 Recharge
...I like trying to work the hold in with the Poison Trap Hold component and use it all the time. I currently have this 5 slotted, 2 ACC, 1 Rech, 1 Hold, 1 End Mod. I wanna see how and what that does but will likely change it. I'm not seeing any big -END -Rec so far.
I'ts not much, but maybe it'll be helpful. If I think of more, i'll post it up.
