Welcome to Mentor Roulette! Extreme primals will come up quite often (usually ARR ones) as new players think it's easier to queue up through the Duty Finder as opposed to the Party Finder, either because they don't know the latter exists or purposely want to run it synced. I feel the mentality of a number of these players is they did Hard mode and they are not expecting Extreme to be that much more difficult, and in actual fact depending how many new players you have, you could spend almost the entire allotted time in duty before something happens (a clear or vote abandon). Unfortunately some players are just not ready for Extreme content and despite offering advice/tips on how to get through it, they can continuously fail what is expected of them to progress the fight. Sometimes it can be they are not quick enough to react to mechanics or they don't quite know their job well enough, resulting in it becoming frustrating for players who are doing things correctly only to get held back by those learning too slowly (even with echo!).
