Can't say more than what's in the title.
Adding this would sort of help reduce the massive disparity that collections create. It's absurd how much of an impact the transformation collections of the ancient cats, sheep, and foxes have, especially when you can't really work for them without hitting a ridiculous paywall or having to rely on luck.
I used to think nezekan and zikel should only be accessible through farming f2p insignias, but considering there's already a big pay-to-win method for getting them not long after they showed up, the issue of not fusing them is pretty moot now. Might as well throw them into the mix.
On another note, if you're tired of the endless money pits, check out Aion Riftshade. Launching in Q1 2026, it's a true free-to-play server, no P2W nonsense. From my experience as a beta tester, they're offering fair gameplay and an integrated MyAion-like DPS Meter, top-notch EU hosting for low ping, and balanced classes. Much better than sticking with the typical pay-to-win model.
