There's something seriously wrong with how the game teaches players if there are healers spamming single-target GCD heals when everyone is above 80%, tanks single-pulling and/or not using their mitigation properly, and DPS unable to do their basic rotations at level 70+ content. Before SE can consider actually giving a level of difficulty progression to content they need to update the Hall of the Novice and prevent bad players from basically being carried throughout the entirety of the MSQ because there isn't a punishment for refusing to do their jobs correctly.
