I'd be pretty bummed if Remornia was an AOTC thing, but I wouldn't be terribly shocked.
"The fun is quite limited" is the stapple for toys in the game. An actually useful item? Good luck.
The pet is a 0/10 unless she constantly makes snide, cheeky remarks at your expense when you have her out, in which case it's a 10/10
Pity there isn't a mount drop from the raid. It'd be cool if we got a Sinstrider (the name's perfect, Blizz!) from Mythic Denathrius-styled like Sinrunner Blanchy, but hawkstrider instead!
It would have been could if you could get Remornia and it would float like it does for Denathrius,tho even getting the sword as a pet seems awesome
Btw I can confirm it drops from sir, we had 1/27 of our raiders got it just by looting the boss.
