Go clear Ultimate then.
Or get a party together and run some old content synced, it's still there and it's still something you can do

If you don't raid and don't craft then I don't get how you expect SE to add enough content to keep you satisfied, it's not like they can realistically add a new dungeon every couple of weeks.
Plus we have a new content cycle coming really soon, of course you've run out of stuff to do since we're at the end of the current one.
