We have a recent example of underworlds band with tufts that has scenic bases. The most likely scenario is that Gryselle’s Arenai bases are still scenic but just that underwhelming.
They've said on the stream that it's less than a half.
And also this from the WarCom article:
That’s not all the Seraphon can look forward to in 2023 – this teaser is just the crest of an enormous wave of righteous reptiles poised to wash over the Mortal Realms.
My gripe with this one is that instead of making an interesting Rumour Engine they've decided to confirm more releases right after the first wave instead of waiting another month or two to give it at least some breathing room.😞
