I just ran a few SBBs back to back with my most recent controller, plant/poison. I have to admit, I was impressed! The debuffs for Poison are not toggles but clicks, and this made it very customizable. Plant with carrion Creepers, Strangler, Roots, Paralytic Toxin (FABULOUS hold that never ceased to freeze the AVs) and of course the toughest little Fly Trap ever as a pet, made short and amazing work of the Casino baddies. Let me put in perspective: we had my troller, 2 defs and one blaster for SBB. The blaster fell off, leaving just us squishies to fight. The defs were rad/ and time/. The biggest damage came from my pet and carrion creepers. Confuse made the Rikti Monkeys and ninjas very easy. It DID take us a while to finish, since the blaster dropped before the 2 final end bosses in the Casino Heist, which left us all of the Arena to do without real damage, but we did so much better than expected! A few faceplants, yes, but less than I usually get running with 'bigger guns' like brutes and scrappers. The debuffs were fantastic and kept us safe and we did eventually whittle them all down and get the badges. Now I don't suggest having a 3 person team without damage, but it's doable and fairly safe and feels just EPIC when you finally finish! I am a big fan of plant/poison now, two sets I never played on Live. I think I was missing out!
I also understand many might think that rad did all the work (and I HUGELY like rad), but I have run my little girl without others too, and Poison is a great set. I really like the way it plays, while plant does some decent damage and wonderful control.
