In these trials, you get synced to the maximum item level of the expansion and have The Echo build up with each wipe and that makes it a lot easier for new players to beat them in a roulette and allows them to overcome DPS checks that they normally wouldn't because of being unprepared. They are still harder than a normal trial though but these things make a big difference and do allow new players to clear a lot of them.

A big problem is how some Extreme trials are labeled as The Minstrel's Ballad so even if a new player has been told to avoid Extremes until later, they don't recognise The Minstrel's Ballad as an Extreme and queue for it.
