I was just in Hullbreaker Isle and the SMN was new which is fine. They had a few other classes but SMN was their highest and they didn't have SCH at all so they aren't primarily a healer etc. What kept happening was the tank would go from 100%, take a tiny bit of damage down to like 90%, and they would be casting Physik on him. As soon as they would take a tiny bit of damage they were doing Physik as well. When we were on the first boss literally it was Physik, Physik, Physik, over and over, like maybe one Bio II and then non stop Physik. I kept telling them to just DPS because everyone was dropping HP like crazy since there was only really one person DPSing but they refused. At one pull before the first boss I had to just let them die because they absolutely would not stop casting Physik so finally I just stopped healing them myself and let them wipe and we finished it without them. On the first boss though we kept wiping because of them, like everyone would be at 100% HP, someone takes the tiniest bit of damage (the kind where it's not even worth healing the person since Medica II would have them at 100% in about 5 seconds type thing) and sure enough you'd see their action bar "Physik, Physik, Physik". As soon as we finished the boss I voted dismiss and the others agreed, but we were at like 25 minutes already and still at the first boss when normally the whole instance should have been done by then. Hate to do that but what else do you do in those situations? It's one thing when someone is new but this is a level 50 dungeon and to not know what your job is is a bit shocking to me especially since you've had to do much harder stuff to get to that point, so not like this is Sastasha normal mode or something where those things are understandable. I'm not one of those players at all, as I'm not some pro so usually second guess myself. But I do know that a DPS that is casting 98% Physik and the rest Bio II and Miasma is not doing their job properly and making it take 10x longer for us. The only way we finished the first boss was letting them die and ME DPSing a ton!
