i wonder if this was intented to work like this or an oversight
How much do you want to be this was an oversight on Blizz's part and soon they will change them for any toon that has them and make them untameable?
DEFINITELY NOT INTENDED, since the toy is no longer available. So get it while you can!
They did. The baby wolf you could take in legion got hotfixed.
What a wonderful time for groups helping others to get the toy to suddenly not exist. I want this pet, but I can't get the toy. I keep dying when I'm almost done.
You can also attack any opposition faction member to turn them hostile for taming.
I don't think it's fair to credit one person individually. I thought of this days in advance and it was the second thing I did upon logging in as soon as the servers went live (the first was trying to tame Mishi, but it's flagged untameable.) Here's my original Petopia forum post detailing how to do this. https://forums.wow-petopia.com/viewtopic.php?f=3&t=26210&p=615140#p615140
Wouldn't this method work on the Ivory Cloud Serpent one as well since it spawns in the same zone and you can use the dagger? Though you'd have to be lucky to get it tamed before people started lasso'ing it.
Curious as to why you think this would be a bannable offense (not being snarky, legitimately curious as I don't know if Blizz habitually bans for mundane things). It's not an exploit that gives the player any kind of advantage.
