This is just a general discussion based on my own curiosity.
I can totally understand that there are definitely collectors out there who have fun trying to own or do everything. I was hardcore WoW player for over 10 years (hardly touched Shadowlands though) and never once had any desire to care about mounts. They all have the same animations and provide the same purpose as all the rest of them. None of the mounts have any cool special abilities or perks to them (except for the two seaters with AH)
I think the only mount I ever really cared about was Invincible and that's really only because I was obsessed with WOTLK and DK has been my main class since Wrath beta.
So for those out there who love collecting mounts, why?
