Unpopular opinion: lvl 50 story dungeons
I really feel the lvl 50 Main Scenario dungeons should have locks so we can't continue until all the adds are killed. This rush to the teleport ends up leaving unexperienced players behind, and rarely do people explain what's going on. This wastes so much exp for those new players. The bosses shouldn't spawn until everyone is out of a cut scene viewer. This way those new players who want to enjoy the content can, rather than being pressured to skip. This roulette is so we help those people, not inconvenience them and ruin their experience when it's fresh and shiny to them.
