Hello Goodbye

[ItMe]

Let us skip straight to doing difficult light party dungeons and progressing that way. The ones you give us to progress with are very easy.
Just ... let us play a game with our friends ya know?

You can skip all the way to the end, you still won't find difficult light party dungeons in progression.
And even then you're not making progress "with friends" because you primarily team up for duties but 99% of the time you're doing story quests alone.
It sounds like you want an experience out of this game (challenging multiplayer campaign) that it's not trying to provide.

I wish you well and hope you find what you're looking for.
