You asked
where and I'll tell you that and
how. (because I feel this question gets asked a lot and not sure it gets covered here so I'll just add my tidbit so it can be referenced)
Pandarian
blues are farmed in
Valley of the Four Winds ((28.34, 30.33) if you use TomTom). You'll be aiming to kill
Stout Staghorns (mainly), along with Kodos and Monkeys when you’ve established spawns,
with a level 22.
Ideal setup would be to have one person in the image I've posted, killing the 3 "packs" circled in black in "setup.JPG". While the second person is at the 2 circled in red in the same image.
You'll want to kill these 5 packs as quickly as humanely possible, constantly running between them, for roughly 5-15 minutes.
When you kill these packs after a certain amount of time the circle that is filled in black on "setup.JPG" won't be needed anymore and the 4 packs will hyper respawn.
Once the 4 packs are continuously hyper spawning at some point the 2 black unfilled circles at the top of the image will be the only 2 packs required for the farm! You'll then have one person on one pack while the other sits the other pack, sit mindlessly for hours spamming whirlwhind.
- To be noted: The packs hyper respawning seems to be determined by speed of clears and only seems to trigger with 2 people minimal randomly. As a solo player you're going to have to run from spawn to spawn continuously.
- I highly recommend making sure this farm is attempted on a random timeline, if you're in normal timeline you'll have a lot of levelers ruining the spawns!
Rough estimates of kills per
hour based on this method + how many farmers:
1 person: 900-1.2k (can't trigger hyperspawn)
2 people: 2-2.4k
3 people: 2.5-2.7k
4 people: 2.8-3k
You can expect
roughly 1
blue per 1-2k kills.
Noteworthy loot:
Gerp's Perfect Arrow,
Daelo's Final Words,
Core of Decency,
Davidian's All-Seeing Eyes,
Endwyn's Toothy Visage,
Hood of Alchemical Vapors,
Zom's Misty Hood
P.S, I'd recommend getting an addon like Hyperspawn (makes the 2 mins before loot expires semi afkable), level up engineering for Loot-A-Rang and frag belt (they help an insane amount), and I'd
HIGHLY recommend being a fury warrior, whirlwind + crusader is insane. Oh and bind whirlwind to scroll wheel, save your fingers!!
If more info is needed let me know in here and I'll edit this post! Also I can't figure out proper formatting.
