Future reference, not everyone can easily use the Mid's links. You'll get more and faster responses if you post the entire build with the data chunk.
BS/DA is one the sturdiest builds available to scrappers. You've really over slotted some powers and under slotted others. Specifically, you've over slotted your resistance toggles and under slotted Dark Regeneration.
You'v skipped Parry, which dramatically improves your survivablility. You also skipped Death Shroud, and important source of AoE damage and endurance management.
Much of your build is bit of a mish mash. You need to decide if you want to pursue a typed defense or a positional build. Either direction is viable but each has it's limitation. Both are very effective.
While were at it, did you go Cardiac alpha slot, or do you intend to? Do you have Atlas and Portal Jockey accolades?
I find my main trouble with carnies on DA is with Master Illusionists. Sine I've got a mostly generic IO build, then I don't have much in the way of defence, and I've been held more than once when a MI and her summons all unloaded Flash and Blind on me.
