Hello all, I just wandering how did you managed to get the Gnarlpine-like skin for your feral form??. I thnik it is from Cata, but don’t know how to get it, and I found NOTHING about this. But still see a lot of druid in-game with it.
I think you’re either referring to a Kuo Tiran druid cat form, or a feral artifact cat form that could be earned during Legion.
Aye, seeing as you’re a night elf, I’m going to have to go with Alliance Druid - Kul Tiran Feral form

Scroll down a little and look at the forms. Look familiar ?
You might be thinking of the Guardian Mage Tower appearance, which is no longer available.
Yeah… this is the Guardian Mage Tower ones.
But I still saw a lot of druid in this form… that mean you can use it only if you unlocked it in the 7.2 I think?
The Mage Tower forms are no longer available. If you didn’t get it in Legion, the opportunity is gone forever.
