Blades Edge Mountains for me.

Argh! I am still trying to find three more quests there. I think it can only be accomplished by doing dailies with the Ogres to get more quests. Ugh. I hate all those stupid crystals and their simon mini-game.

On the other hand, if you have never quested there it might be easier because you can get bread crumb quests and they will count. But I leveled there a bit and then decided to go back and get Loremaster over a year later. Terrible! XD

ANY mid-high level zone in the old world before cataclysm. Zones in Kalimdor whose quests started or ended in Booty Bay.

As for Outland, i vote for Netherstorm - seems like half the quests there start in Nagrand or Shattrath

I have to say Ghostlands and whatever the Alliance equivalent is. It doesn't seem too bad until you realize you still can't fly there. The one redeeming feature is that you find Sylvanas's locket there.

That stupid item drop that starts quests helped me complete my last 3 quest in blade's edge awhile back. I'd been stuck at 3 left for like 7 months before finishing it.

The addon QuestCompletist is a great help for any aspiring Loremaster. It lists every quest for a zone with details on where to get the quest and can query Blizzard's database to show which ones you've done. Even warns you if there is a breadcrumb quest available for the quest you are about to pick up.

Also, I don't remember having to do dailies to finish Blades Edge. In fact, I'm pretty sure I had at least a few quests available in each Outland zone after getting Loremaster Outland.

RE: Blade's Edge -

I seem to remember getting the LM sub-cheebie without getting too far into Og'rilla. I don't remember clearly, though, because it's been so long and I REFUSE to subject myself to LM again.

EveryQuest is the completionist addon I used. It separates quests into professions, dungeons, raids (what few there are), holidays, etc. It plays nicely with LightHeaded (it brings WoWhead into the game - VERY handy for leveling).

Yeah, I was using Everyquest when I got my Loremaster. I switched over to Quest Completist at the start of Cataclysm when EQ took a bit to be updated. Either one would be a help for any person going for LM.

For me it was a toss-up between Nagrand and anything to do with godforsaken Blackrock Mountain. Nagrand because someone screwed the hell out of the Garrosh/Thrall quests and now Horde is like 3-4 short of being able to complete the zone (I had to go get Loremaster in all the other zones to get a breadcrumb to come back to Nagrand for the last 3. wut) Blackrock Mountain because I shouldn't have had to spend 6 hours in there getting horribly lost, getting out, turning quests in, then getting another one to go back in there. I won't even go in there as an 85 now.
