It already exists since heavensward, just add it as a mount already.
People really want a PvE Hellhound type mount, because PvP hellhounds are never gonna come back and PvE bois are malding about that fact.
This one even has wings and would be superior, give it to them - it's pretty cool and edgy. If nidhogg gets mad because we ride his wife then just give it a different name than tioman, whatever..

I know the chance is abyssal low for a community mod to see this and actually link to the dev team, but at least I tried
