Had this issue in in the level 61 dungeon the tank (with the new person icon ) would not use shield path lol I was the healer And explained what it was and had the team wait five mins to help him out, I was sadly ignored and hit with a "my sub, my game play" and the dps didn't want to kick him because they already waited 40+ mins to get in there and I didn't want the penalty for leaving :/ I still have no clue how we completed it but the dps were getting smashed lol
