02) Next to you at the watchtower, turn in (if you have it from the Durotar section) "Ak'Zeloth" (62.20), accept "The Demon Seed".  Then loot a Flawed Power Stone from the table next to you.  NOTE: The Flawed Power Stone item received only lasts 30 minutes, so you need to do the next few steps somewhat quickly (but you should have plenty of time).
Hunter, 2a)  Hunters, while on your way to XRs, abandon your scorpid and tame a Savannah Huntress cat for your new pet (this is for better DPS).  Try to get a level 12.  Make sure you use Beast Training on your spellbook to train your pet other abilities.

02) While working on the following steps, also start working on "Plainstrider Menace" and "Raptor Thieves" by killing plainstriders and raptors all around the fields of the Barrens, but don't make it your main priority:
03) Go north up the big mountain ramp (begins at 51.22).
04) Once you get at the top do "The Demon Seed": go in the small cave and use your Flawed Power Stone quest item on The Altar of Fire (48.19).  NOTES:  Watch out for a rare elite named Rathorian, he is very dangerous.  If he is in the way, then either try to team up with someone to help you kill him, or this quest can be skipped.  His respawn is every 5.5 hours.
05) Go east and do "Disrupt the Attacks": kill the needed Razormane mobs (all around 54.27).  ALSO: Back in the Razormane camp is a barrel called Chen's Empty Keg (56.27), loot it and accept the quest from the item received.

03) Hearth to XRs.
04) Go to the orc at the bottom of the watchtower and turn in "The Disruption Ends" and "Supplies for the Crossroads" (52.31).
05) Turn in (if you haven't yet) "Plainstrider Menace" (it should be done by now) (52.31), accept "The Zhevra".  NOTE:  If "Plainstrider Menace" is not done yet, you can find a lot of Plainstriders just around the outskirts of the XRs.
NOTE:  You should be level 14 right now, if you aren't then grind on any mob until you are.
06) South in XRs, accept "Consumed by Hatred" and "Lost in Battle" (52.32).
07) At this point, I make sure I have 3/4 six slot bags, if I don't, I buy them at the bag vendor (the southern most vendor in XRs, 52.32).  Make sure you are repaired/resupplied.

ORC & TROLL ONLY:
NOTE: This section is for Orcs and Trolls only.  Or if you really need to get lvl 14 spells/abilities in Orgrimmar.  And I only recommend doing this if you need to take a break IRL (such as to eat or bathroom break) as the xp/time is barely worth it.  Otherwise skip this and move on to the next section below.
01) Go to the Wind Rider Master (51.30) and accept "Ride to Orgrimmar".  Then take a ride to Orgrimmar, Durotar.  Rogues should have already done the "Ride to Orgrimmar" quest chain earlier, but you can still go to Orgrimmar to get your level 14 spells/abilities if you want (just ignore this quest chain)..
02) At Orgrimmar, go to the Inn and turn in "Ride to Orgrimmar" (54.68), accept "Doras the Wind Rider Master".
03) Get your level 14 spells/abilities.  Hunters SKIP this step as the lvl 14 abilities are not worth the time to get.  Warriors SKIP this step as the lvl 14 abilities are not worth the time to get.
04) Go up to the Wind Rider Master (45.64) and turn in "Doras the Wind Rider Master", accept "Return to the Crossroads.".  Then take a flight to Crossroads, The Barrens.
05) NE in Crossroads turn in "Return to the Crossroads." (53.30).

01) Go west of XRs (grinding on zhevra, plainstriders and raptors along the way), to the orc in the burrow and accept " Kolkar Leaders" and "Centaur Bracers" (45.28).
02) While focusing on the following quests, also kill any Plainstriders, Centuar, Raptors and Zhevra along the way, but don't make them your main focus...
03) Grind your way to The Forgotten Pools and do "Fungal Spores": loot the Laden Mushrooms around The Forgotten Pools.  And discover the fissure for "The Forgotten Pools" (under the water at 45.23).
04) Do "Kolkar Leaders": grind your way to Barak Kodobane (43.24), and kill/loot him.  NOTE:  "Centaur Bracers" does not need to be completed now.
05) Go NW to The Dry Hills and do "Harpy Raiders": kill/loot the harpies (around 41.19).  Watch out there is an Elite that wanders around in the area. Warriors, the harpies here can be tough and now would be a good time to make sure you have the Hamstring Method down good.  Be careful and use all the buffs you have against these harpies.
06) Grind your way west (at 35.28 in the Barrens) and accept "Goblin Invaders" and "Avenge My Village".

15-16 Stonetalon Mountains
01) Go west into Stonetalon Mountains and do "Avenge My Village": kill the Grimtotem taurens (around 81.90).  TIP:  Kill the Grimtotem Sorcerers first as they do a lot of damage.  Use range pulling as much as you can here and be careful, try to find help if you can as this can be hard to solo for warriors.
02) Once done, go back and turn in "Avenge My Village" (35.28), accept "Kill Grundig Darkcloud".
03) Go back into Stonetalon, to the path that goes up into Grimtotem post (starting at 76.89).
04) Do "Kill Grundig Darkcloud": kill Grimtotem Brutes and also kill Grundig Darkcloud, he is standing on the steps outside the hut (74.86).  You will need to use range pulling on most mobs here.
05) Warriors:  This step is near impossible to solo alone, if you can't find help then skip it unless you really want to try it: Accept and do the escort quest there ("Protect Kaya" 73.85 in the hut). TIPS:  Try to keep aggro off of Kaya Flathoof, as she has low HP.   Kill the Sorcerer first that pops out during the one battle you have to fight.  Fear the Sorcerer first that pops out during the one battle you have to fight and immediately use the Voidwalker to Torment the melee mobs off of Kaya.  If it's too hard for you, skip it.
06) Once done, go back and turn in (if you did it) "Protect Kaya" (at 35.28 in the Barrens, #2 on map), accept "Kaya's Alive".  Also turn in "Kill Grundig Darkcloud".

16-20 Barrens
01) Grind your way to the orc in the burrow and turn in "Kolkar Leaders" (45.28).  Accept "Verog the Dervish".  Also turn in (if it's done) "Centaur Bracers" if not don't worry.
02) At this point, make sure "The Zhevra" is finished, kill/loot Zhevra while you work your way to the XRs...
03) Go to XRs and turn in all quests and accept new ones:  Turn in (next to the Flight Master) "Fungal Spores" (51.30).  Wait a few seconds then accept "Apothecary Zamah".

08) Grind your way down south (to 49.50) and do "Lost in Battle" (Manrik's Wife): She's laying dead by the hut, west of the bridge.  Simply examine the Beaten Corpse.  Also as you work your way down south, grind on mobs and make sure you are at least 800xp from level 16.
09) Go south to Camp Taurajo (CT) and accept "Tribes at War" (quilboar in the cage at 44.59).  And get the FP there next to you from the Wind Rider Master.
10) Follow the path west into Mulgore and as you enter on your right, die on purpose, then res at spirit.  If you are a Tauren, just fly to Thunder Bluff, Mulgore and skip to the TB section below.
11) Follow the path north and then get on a Lift (at 36.30 in Mulgore) to go into Thunder Bluff.

Thunder Bluff

03) Go up north to The Dry Hills (harpy camp) and do "Harpy Lieutenants" (around 40.17): kill/loot the Witchwing Slayers (they are the only ones that drop the rings).  Watch out there is an Elite that wanders around in the area.
04) Grind east and you can get repaired/resupplied from Vrang Wildgore next to the hut (at 44.12).
