MORE PETS/////MAGICAL PETS//////PET VARIETY
I feel like your title is really really annoying and is likely to get some unfriendly moderator attention, and this isn’t appropriate for a question post.
But other than that, I think it would be cool if not only ranger pets but Necro minions, guardian spirits, and engineer turrets all had quests and/or items to be earned or completed for new skins, including ‘legendaries’ of a sort.
