As the title says, I would like to see this happen. The models are already there, they would just need some reconfiguring along with some tweaks. I don't know how many times this as been said or what not seeing as this is my first time actually being able to access the forums. However, I would like to see this happen, and probably many others too.
In total, with the models available that is 2 pets and 2 mounts seeing as there is the grey wolf model and the black wolf model, but of course they could make it 3 or more with a simple color change. I don't know if something was said in the past, or if nothing was said at all because that would take a large amount of time, sifting through a lot of topics.
In retrospect, wolf mounts and pets would be cool to have.
