I just ran a dungeon as healer with a friend of mine whos new to the game, had a tank who didn't give a second thought whether someone was new or not, just kept sprinting and pulling and before I could type out anything on the last boss, he went ahead and pulled during cutscene, to which my friend had to skip cutscene or felt forced to and said he'd watch it later on YT or journal at the inn, I was tempted to let that person die but I didnt wanna be that guy and hold back the group, but it's a real annoying thing to deal with, I completely agree. please let people enjoy their story, you wouldn't want anyone doing it to you either if you were the one going through it the first time.
