Northrend leveling guide

My feeling in the future (if i ever level another toon) is to skip the known slow areas, could speed up leveling by 50% i think. And above all, avoid instances like the plague. They are horrible time investments for the XP return.

Some good quest hubs (off the top of my head).

Borean Tundra:
Warsong Hold
DETA
Taukale Village
Borgorok outpost

Dragonblight:
Actually all the quest hubs are pretty non-parallel. Agmar's hammer has a few parallel quests, as does Venomspite (the New heathglen quests are good xp/time)

Grizzly hills:
Conquest hold has a few parallel (or easy) quests. If you do all of the quests from the hub you can get the gladiator quest series (Conquest Pit), which is yet another arena quest series. THese are so good for xp/time if you can get a group. Avoid the troll mojo quests like the plague.

ZulDrak:

Skip Ebon Watch. Do Light's Breach, and Argent Stand. Also the small group of guys just northeast of Ebon Watch has a good quest hub. Do ZimTorga, and def. Ampitheatre of Anguish. The 4 mini quests for Argent stand (Troll Patrol) has an achivement if you can do it within 20 minutes, and rewards supposedly 60-80kXP.

Scholozar Basin:

Do all of Nesingway quests. Do Rivers Heart. Skip the rest. Most of the quests in this zone are non-parallel.

Storm Peaks:

Do K3, do the Hodir quest line (which opens up a nice quest hub at Brunnhildar village). You can stop when you get to the Hydemeet, or keep pushing to open up Sons of Hodir. Do the crash site (Gromarsh) - this unlocks several quest hubs, one which is good and easy is for the Earthen just NE of the crash site. Quests in this zone are pretty fast IMO.

Icecrown:

Not an expert on this, but do Argent Vanguard to unlock Argent Pinnacle? quest hub. Do the Ebon blade quests which unlock dailies which are quick. Much of the quests here are either dailies or group quests, so this zone isn't all that great for leveling.

Howling Fjord: I never really did this zone in full. I'm sure it's like BT though.

Overall I'd say

Borean Tundra 68-72
Dragonblight 72-73 or 74
Grizzly Hills 74-75 or 76
Zuldrak 76-77
Scholozar (Nessingway quests only) 77-78
Storm Peaks: 78-80.

Once you finish the major quest hubs in Dragonblight go to GH, don't finish the zone. Ditto for GH, ZD, and Scholozar. SP and BT are the only zones that are decent for leveling to do in full.
