Yeah, I figure this was one of the added factors that were intended to make the usual steam-roller slow down a bit and have to consider what they were doing. I just ran a 2-star and had to learn the hard way (three deaths iirc) that my stalker really had to just sort of hang back and do, uh, well not much at all, while others finished those off from a distance (I might have started out hitting them, but started backing off pretty soon). And that I had to tab through the crowds we were fighting to see if there was a crystal that I needed to avoid. I can't say I love this either, but I'm not planning to make a habit of HARD STUFF runs anyway.
