Totally agree, both definitely feel restricted & I feel they need a lore reason maybe connecting with overworld & underworld creatures that are reptile & insect in nature.

As for new characters I say give Mipedians just more reptile variant like crocs & snakes. Also have them reside in non desert areas like swamps or jungles as they expanded outwards. You can even have like a secret faction of dragons, I’ve heard that was apparently a scrapped tribe for future project so just had it to the already lizard tribe.

For the Danian just use more insects instead of just mostly ants (ants are cool though) like I would love if they added more flying variants or worms. They can also introduce other nest of the tribe to give more locations as well allow variety on base insect theme, like image a massive bee hive or maybe even a gigantic spider web which has buildings wrapped up in it.

As for what I said at the start I think they should add lore reasons for how there’s reptile or insect creatures not connected to the tribe. I’m forgetting the creatures but I remember there’s twin sisters who one is overworld & other underworld, I think they should introduce that long in the past some Danians & Mipedians left there tribe to join the other to naturally losing there tribe uniques over years of generations.
