When lvl 50 was the cap, you could farm in Dragonspyre for your gear.
When lvl 60 was the cap, you could farm the Waterworks for your gear.
You could farm Mirror Lake for crowns level 70 gear.
What happened to Avalon? I think that they should open Barkingham Palace in Marleybone and add an 8-person sigil to it, and add an extra challenge for players.
Or, a side quest world could be Street Level of Marleybone. I noticed on every street, there is a door: "To Street Level." You can't go in. I think Street Level could have a secret entrance to Barkingham Palace instead.
