Definitely agree with Worldpvp here. While I don’t have much to say about the rest of your suggestions, returning glad mounts or even recolors for any content are bad ideas IMO, especially if it isn’t even PvP content. Blizzard was originally going to use a recolored green MoP gladiator mount for one of the cloud serpents introduced in 8.3 world content and got a lot of backlash for it and so changed their minds. I’d really prefer they didn’t try to do it again.
