Get Sojourner of Hallowfall
Atherne has all of the major achievements except Sojourner of Hallowfall. There are two time gated quest sequences, as in a week between them when you'll be able to do the next one, and I thought I got the third part of one of them today, but zip. This, along with the whole time sink area with the all the light the fires and blah blah blah are making Hallowfall my least favorite land in the game.
Raise Rep with Azj-Kahet
Particularly with The Vizier. He and I are at Crony level, if you can imagine.
Level up The Big Four
Get Proudmoore Paladin, Earthen Ring Druid, and the Blackwater Raiders Fire Mage to level 80. The Paladin is at 77 1/2, and has only been out for a few days. It helps so much that Atherne did every single thing everywhere, so I know where to go and what to do. I've got the Mage doing quests and World Quests to gear up quickly, as Mage isn't one of my best classes to play. Druid two should be heading out soon. All should be 80 by months end.
Tradeskills
Honestly tradeskills are a super butt pain, requiring loads of materials to trash with experimentation, and little to nothing to show for it, even for Cooking. Knowing this now, every character is loading up on every resource possible before they even start to craft.
Do Every Quest, Every Delve, Every Dungeon Before Moving On To The Next Area
As much fun as it is to move along to the next adventure, leave no Quest or Delve unturned, is my motto.
