I came back about a month ago, I've been doing old missions, leveling NPC and doing some old content as a duo (sea/sky/salvage/Aby etc).

Is Adoulin worth buying for someone that will be duoing (in Eminence gear) or is it all full party/alliance content? Not counting the obvious things like story/areas. I'm just considering whether to buy or not buy based on gear I can obtain from the new endgame areas of which I will only be duoing.
