SE just need to go ahead and fix it. Chop it down 4 man dungeons because it never needed 8. Make the cutscenes skippable and split it up so the actually important cutscenes don't play mid dungeons. Like prae should end before the nero fight and have two trials to finish out the rest of the content thats in it now.

If you have to heavily bribe your veteran players run content for new players you have messed up.
