Yeah, the two main scenario ARR dungeons are the worst offenders because they can essentially be done by a party of four. Keep in mind that while you may want to enjoy your story the first time, these players are probably playing that content hundreds of times because SE commonly has the Main Scenario end dungeons give the most tomes. If you want to enjoy the story of the content as you are playing it, you should form a party of either FC members who are willing to wait, or make a PF group. If you can't, then that should shed some light as to how much of a minority in this situation you really are.

The good news is that Heavensward's Main Scenario dungeon has less cutscenes and doesn't have them placed randomly in the middle of a battle. They also purposely limited the item level to the point where heals and a tank are very much a necessity.
