Ive run through this list of quest twice. The first time was with a paladin and 4x druids and i didnt have any real issues, even with the dungens. Second run is with a 80 paladin and 4x shaman and of course its a cake walk with the 80.

Skettith Halls or whatever that zone is with the mind control guys was a pain and the fear bombs in the slave pens too. Im thinking about maping out the other outlands zones as well. If they reduce the xp needed to level etc when the next expando pack comes out, it MIGHT be worth it to stay in outlands till like 73 ish as northrend is not very MB friendly when it comes to the quests, other than the dailies.

I also recomend doing the Spooregar rep grind to neutral to unlock all the dungen quests in Underbog. With the upgrade to rep they put in, it shouldnt take more than 20-40min killing bog lords to get it, and its worth the extra 44k xp.

If your boosting, just grab the most valuble quest reward. The only rewards I kept for my shamen on this run were the blue quest rewards.
