Next Onyxia's Lair filler raid?

[Takanuka]

Deathwing's Lair

• Since we are in a alternate Draenor reality would serve the same style as Onyxia's Lair raid but as a filler with maybe a pre-armored Deathwing skinned mount dropped?

Since 6.2 looks to be the endgame content despite not seeing Gul'dan falling which he might in the end of the legendary ring quest but idk.

And what is this please let me know the second picture that island neighboring Talador and underneath Nagrand? Since the giant island sw of the entire continent is the ogre capital and the one near Gorgrond is Farahlon.
