This ^^ almost exactly! Done with all 10 classes on ally server, now running through horde server. (although if I am going to be near pc for a while I'll do deepholm and TH kicks quests too as its quicker)
Archaeology is not 100% afkable, due to stucks. I would say BGbuddy is the only 100% afk thing. But leveling with Kick's profile is 100% recommended from my side.
If you blacklist the right locations in Kaimdor and your Horde you can do Archaeology from 80-85 with no stucks. I do it alot. I think there are 2 specific locations i had to BL.
I have never bought any Cata greens on any of my chars and I never encounter any problems in the new zone Im going to, be it Hyjal, Uldum or Twilight The first quests are specifically formed so that you get some new gear fast and can continue without any difficulties.
If you use MCFly's Unstuck Plugin, you can 100% afk it in the Easter Kingdoms, Kalimdor too, never tested it there.
Dungeonbuddy needs an update so you can reque without a party. If they release a fix I'm sure alot of people will grind Instances. Instancebuddy isn't supported anymore, unfortunately. So untill there's a fix for Dungeonbuddy I believe Arch or BG's are the only ones 100% afk. I run Kick's profiles and help them a bit when necessary till 84, then just BGbuddy so I have 4k Honorpoints when I hit 85.
Leveling 80-85 with instances isn't advisable. The xp is pretty weak, and the dungeons aren't currently 100% AFKable. If you're able to bot on a Call to Arms weekend, that is a pretty efficient way of leveling, high xp on wins. 80-82 is best with questing though.
people saying that they get owned with their LK gear doing 80-82 quests - spend about 10-20 mins doing the first couple of quests in hyjal manually and you will get gear that boosts your toons survivability by a lot and then just afk the rest of hyjal
This is what i do: 80-82 Hyjal entirely [100% AFKable] 82-84 Archeology-BGs [100% AFKable] 84-85 Twilight. Babysitting just because is so damn fast compare to anything else plus i get nice gear for Heroics/BGs
I've read some posts about overpopulated bgs with BGBuddies, but i believe this is happening in EU. Rarely see other char doing the same thing than mines in bgs.
