So now Thralls need regular food?

You know what funny that they adding this because they don’t know how to separate their code between pet and thrall.
Not sure but just a theory, maybe went they added this new content “feeding your pet” they realize now that thrall somehow had to feed too because they using the same code which mean they had no choice but to lie and announced they had a “new feature” that you to feed thrall as well.

Don’t you think is strange how the pet and thrall work virtually a same? you can’t mount, you can’t have more than 1 to follow you, and they will teleport next to you if went away to far or because you climb up a mountain.

Not to mention they had to train the same way as Wheel of Pain.
