Plesioths return is something special; we get to fight it in its natural element. Lavasioth, on the other hand, cannot be fought in the Lava. Personally, Agnaktor makes up for it better. In Unite it only acted as G-ranked pain in the ass (and it did appear in high rank via a dlc quest). I don't object to the return of carapeceons, but their is very little possibility of Lavasioth.
