It definitely recieves shadows from the environment, I might just turn off cast shadows, though. I don't know.
So the REAL reason 50 draw call TDA's were eating up performance is because they're recieving shadows and probably casting as well, meaning they were 150 draw calls effectively. Then multiplying off of each others. 
I'm not too entirely certain if around 8 materials and recieve shadows on with cast shadows on is a problem, I'm very tempted to turn those features off, now.
