So, I'm just gonna post some potential buff material.
Ivory Lagiacrus: Stated to keep up with Deviljho, meaning it should scale to speed/dura/AP (Which makes me happy because I think ivory Lagia is amazing). We could most likely set up a seperate key for it.
Nakarkos: Casually preys on Brachydios and and Agnaktor, as well as Uragaan (which even Deviljho steer clear from, ONLY for their power), so he should be at around MCB, or moer likely Small Town while being High Hypersonic. These guys ALSO keep up with Ceadeus, though more often then not, Ceadeus are superior. Regardless if we keep Ceadeus at Town Level or if we buff it to Island Level via it's lore-based feats, this should get scaled below Ceadeus.
Ceadeus: Stated that Adult Ceadues prey on Nakarkos, so it should most likely be scaled in speed at least. Also, while I do remember being told that we should get a calc done for Ceadeus' Island sinking feat, I don't think we actually can. There are no good, full shots of the island in question, and even if we did get a good shot, we don't really have any means of finding a size for the island. So all we are left with is the fact that is has sunk and island, and it would have sunk another island should it have gotten serious.
Whatever we get as a result of this (And by that I mean whether we change it to Island Level or keep it at Town Level), it would still provide a noteworthy AP rating for Abyssal Lagiacrus and Nakarkos, though these two are slightly weaker then Ceadeus.
Abyssal Lagiacrus: Implied to be near equals with Ceadeus. It should certainly scale to it's new speed, Mach 29/High Hypersonic. Whether we decide to keep Ceadeus at Town Level or Island level, it would then provide a buff to this one's strength and, rightfully so, make it the strongest Lagiacrus.
Kushala Daora: Stated to create Hurricanes and large Thunderstorms, which, iirc should at least be Large Town Level. However, it is ONLY this powerful with it's storm generation. Physically, it should most likely be Small Town Level, as a Rajang can threaten it's life on most occasions. Also, thanks to The Perpetual in the last thread, we found out that it's attacj speed is Mach 154 via dispersing clouds covering the sky all the way to the horizen.
Chameleos: Stated in the Kushala Daora Ecology that these two compete, meaning that this monster COULD be Small Town Level as well, and comparable in speed.
Amatsu: Stated that it has superior storm powers then Kushala Daora, though it likely isn't much stronger then it physically, and likely should be scaled to Kushala Doara's stats, mostly.
Dalamadur: The only thing I can think to add at this point is to at least buff it's AP to Small Mountain, given how casually it it stated to break mountains. Also, it was stated on two occasions that the "meteors" that it summons are actually small fragments of our sun, which can travel form the sun to Earth anywhere between 5-10 seconds, meaning that, with this ONE attack, it could have FTL attack speed. Everything else should likely stay the same, though.
Any thoughts or doubts on the material above would be appreciated.
