From what I've seen, everyone seems to have a problem with the Sacrament right after the Timestop. Myself included, it took a couple of lasers to the face and back for it down on me he's going to do that everytime. And the game designer's saw that coming too and showed it to us in the cut scene before hand too. The don't stack with a green arrow mechanic gets picked up pretty quickly, but I repeatedly see people not moving out of the way of sacrament again and again.
