Hey, thought I'd just list what pets I used to beat the new elites.
Dno if they're supposed to be hard, but I did em all on first try.
Was considering doing a team with life exchange, but it made the whole thing seem boring so I skipped that, dno if it even works, but I guess you can try if you want ez mode on this whole chain.
Listed em by order I used em inn.
No-No: Highlands turkey, jade owl, deathwing (forgot to change him to wisp, but worked well, didn't have to even use him)
Ti'un the Wanderer: Highlands turkey, jade owl, wisp
Kafi: Tranquil mechanical yeti, clockwork gnome, wild golden hatchling. call lightning -> turret, didn't even get to use hatchling.
Dos'Ryga: Highland turkey, lil deathwing, snowy owl. Deathwing did the kill, snowy owl was not used, but I guess predatory strike would have been nice.
Lucky Yi: Molten hatchling, Kun-lai Runt, Flayer Youngling. Soloed by tanky hatchling.
Greyhoof: Tranquil mechanical yeti, Clockwork gnome, Snowy owl. Yeti got him low so just finished with owl.
Skitterer Xi'a: Shimmering Wyrmling, Jade owl, Snowy owl. Wisp might have been better, but wyrmling got him down a little and jade owl finished him.
Ka'wi the Gorger: Flayer youngling, Kun-Lai runt, Snowy owl. Finished with first 2, rampage ftw.(H'es a critter although wowhead stated him as a beast)
Nitun: Darkmoon Glowfly, Molten Hatchling, Snowy owl (guess this would have worked on some others too, dot him up with glowfly, tank with hatchling, switch back, dot and finish with either one)
Gorespine: Tranquil mechanical yeti, clockwork gnome, darkmoon tonk.
If anyone has better suggestions it's cool, I just wanted to share what I used.
