That picture has alot of droids in them. The question is, how many of them are active and combat ready? Probably quite a few, but I doubt all of them are ready.
Also werent those assassins suposed to get stronger against force users? i mean they were trained for that specialy. If i recall correctly from KOTOR II.
Well, I haven't played the cut content...
