What you will require for this is not being "forever alone", a lvl 60 friend and a pony staff.
Do 1st quest by yourself.
Before picking up rumford at the gate leave game and set it to t6 and invite your lvl 60 friend to group, game will scale down to your level instead of lvl 60, so you will get to 20+ 1st run, you do rumford at the gate quest and turn it in and then go whimsyshire.
Every next resume you port to old ruins waypoint and head to whimsyshire
From everything i tried, whimsy gives the most XP
