I have been boosting in Shattered Halls all the way through to 70. My Shaman are currently 67 and a bit.

Once they hit exalted with Honor Hold I was thinking of going to Magistars Terrace. The reason I havn't gone to any Northrend instances is I am waiting on the Battle.Net Account Merge Cooldown so they can go on the same accounts as my WOTLK accounts.

I did Underbog till about 64 - and those Sanguine Hybiscus sell for heaps on the AH - was making alot of money as you can turn them in for rep - but I had to change it up for Shattered Halls because my brain was hurting. I'm hating Shattered Halls but only have 5k rep to go - then I might as well finish of my mains rep in Magistars.

I boost with Shattered Halls from lvl 65-68 then to Northern. Use 80 pal in pvp gear with some lvl 80 crafted defense gear. can solo instances with out healing and makes good exp runs. at 71 go to AV. much faster exp per hour.

If you listen to the video he says no one is getting XP the only thing he said about bringing lowbies into kara was about gearing them up. So Kara <> XP

http://www.wowwiki.com/Formulas:Mob_XP

(elites in instances give 2.5 * XP when solo-ed; untested for normal mobs in instances - Stilpu) (confirmed zero XP at lv 58 in Molten Core, at lv 69 in Karazhan and Zul'Aman. confirmed XP gain in Zul'Gurub when a lv 56 dinged 57 but exact amount earned is unknown - Ishotala) (Some monsters, like in the Amphitheater of Anguish, give the doubled exp PER player. If you do those quests with less than five players, you'll get more experience than this formula. The total amount of exp they deliver is 10 * normal_XP. Has to be confirmed, through. pikachuyann)

So wowwiki is usually dead on with most of the information. Did they recently change this?
