old news no doubt but I didn't play MoP and just started doing pet battles recently. What shrine is being mentioned? is it some area in the city for horde/alliance? trying to find w/e gate is blocking Farmer Nishi, Lucky Yi, etc thanks much

He means the main city for your faction in MOP, where your portal takes you.
Horde: Shrine of Two Moons
Alliance: Shrine of Seven Stars

If you're a tryhard like me (at least, I am during pet week), here are all 21 (spirits, tamers, and beasts), listed in the optimized order set forth in the image linked above on 3 May 2017.

How do I force a Tom Tom macro likethis to do the waypoints in the order they were written? If I have it add next closest automatically it goes through a different and longer route.

The Eternal Strider is a must for Farmer Nishi. You can kill Siren and Toothbreaker with it.

For Aki you need to use a Hopling because really Stormlash is the big danger. I find if you use a big critter killer, like say Xu-Fu, and switch in the Hopling for Stormlash, you will increase you chance of success by a lot.

Note that for all the tamers, except Zusshi and Beasts, you can leave a level 1 toon at the pet battle and just switch between toons. On rare occasions a hawk will come out of nowhere on the Thundering Spirit. : (

Im lazy and needed this... :)

It would be super awesome if you could add the breeds for the pets you are suggesting. The most awesome thing would be, if you made a seperate tab with various different useful pets and their best breeds. :)

Hey Louk!
Almost all my strategies (99%) do not require a specific breed :-)
I hear you, and such a guide of recommended breeds for certain pets would make perfect sense, but right now I am focusing on other goals with Xu-Fu's guides.

If you have a quick port to your faction's shrine (e.g. as a Mage), you can use it after Water Spirit and Mo'ruk to get to the next trainer faster.

I'd like to see a map that includes all of the Pandaria activities (Beasts, Trainers and Spirits) at once, but I have no idea where it would be put. :)

I often miss that pesky Water Spirit. :P

This is the solved TSP for a complete circuit of all 21 fights with no teleporting: http://i.imgur.com/EwNOFZi.png

Other than parked alts or strategic hearthstone attunement, it seems your shortest travel distance is to make two sweeps starting from Vale (NW route from Farmer Nishi, clockwise spiral from Thundering Pandaren Spirit for the rest), or [Alliance] one from Vale and two from Paw'don village. Unfortunately, the Peak of Serenity (monk teleport) does not seem to be a shortcut to any of these (the closest point is Kafi and Yon is closer).

(Anyone who would like to make a prettier graphic is welcome to do so without attribution.)

I've tested this now. With efficient teams, no bad crit luck, and only a little stopping to hit rares or gather, an Alliance character could battle from Shrine to Nishi to Zusshi in about 25 minutes, from Paw'don to Gorespine in about 17, from Paw'don to Nitun in about 6, and from Shrine to Whispering Pandaren Spirit in about 7. Taking four trips cuts out long flights of nothing except for the one to Mo'ruk. Incidentally, I have slow loading and it is still slightly faster to take the Dalaran portal to Shrine than it is to fly back from WPS. All in all, this takes longer than most people would want to make a daily routine even in the best of circumstances.

One good route for Horde is to pick up Beasts of Fable quests, then start with Zusshi (AFK flight path to or hearthstone at Shado-Pan Garrison / Isle of Thunder), to Nishi to Mo'ruk to Gorespine; port to Shrine, then sweep the rest starting from Thundering Pandaren Spirit.
