I think what he's getting at is that since there is now a classification for monsters that share a similar body structure and details of that class, that they should make any new monsters who's appearance, behavior, and body type qualifies under the new class part of that class. Those monsters being used or made after Portable 3rd should have their classification updated.

I think the general problem is that we don't really know what the qualifications for a fanged wyvern are. In portable 3rd, jinouga was the only fanged wyvern, and jinouga happened to have a body structure and details similar to akantor and ukanlos who were still classified as flying wyverns. They all had fairly developed forearms, smaller, less developed hind legs, vestigial wing claws, a thick tail that is relatively low to the ground, and a generally thick upper torso.

I don't think the problem is, "This is what they were originally, so we should keep it that way." It's defining what makes a monster a fanged wyvern. So far, we've only had one monster to base the class off of, and the only other two monsters that share similarities to jinouga that were used recently and even in the same game remain classified as something else. So the qualifications for a fanged wyvern may not be what we think they are, preventing certain monsters from being reclassed, or classed differently upon their release in a game.

Either that, or frontier just doesn't want to add the fanged wyvern class to their roster of monster classifications.
