I said earlier I put more blame on Blizzard for allowing someone to queue up for the dungeon without first having unlocked and gone through the dragonriding tutorial. I don’t blame the OP for that nor do I blame the party for not being willing to deal with it. In the end, the will of the rest of the group matters more.
Just like IRL ignorance doesn’t just get you out of punishments for breaking the law. You may garner more sympathy and get reduced sentences, but it still falls to you in the end. OP was an anchor to their group no matter if it was intentional or not and they got dealt with appropriately. Trying to shift the blame to the other people for not being in a position or willing to cover for their ineptitude isn’t right.
