I really think Juliette just became the new big bad Hexenbiest on the block with Diana thrown in occasionally. They could've had Adalind do similar things but why do that when Juliette already does them?
On a similar note, this is the reason I liked them using Trubel only occasionally. It would be boring to watch her do basically the same things Nick does. I don't think it's a coincidence that Trubel showed up in late season 3 when Nick was about to lose his Grimm. She then left in the episode after he got it back.
