My problem with Aetherdrift's factions

As the title stated, I've noticed a problem with the new factions introduced in Aetherdrift. I don't think any of them are intrinsically bad, at worst they're silly and one-dimensional like the goblins and Keelhaulers or feel too similar to an already existing theme like the Alacrians. Hell, I sincerely hope that the Guidelight Voyagers will come back in Edge of Eternities. But with all of the cards that these factions are getting, it seems like they're taking up space that should have been used for Avishkar, Amonkhet and Muraganda.

So far, there have been absolutely 0 nonlegendary aetherborn, no gremlins, very few vedalkins or dwarves, and considering how the secondary antagonistic forces in the story are Consulate remnants, the complete lack of cards featuring them feels weird. Amonkhet has had better representation, but there's a definite lack of the desert horrors from its first appearance. Not to mention that the Chitin Court, a faction at least partially focused on the Scarab God, doesn't seem use the Eternals? And Muraganda has had great world-building in the Planeswalker's guide, but I don't see a lot of representatives of those civilizations in the cards.

Maybe these issues will be fixed with the remaining cards we haven't seen yet, but I don't think there are enough left to address all of my issues. I feel like if they had cut some of the sillier or more repetitive new factions/deck archetypes in exchange for more teams from Amonkhet and Avishkar, or a vehicle-hate archetype for Muraganda, the set would do the planes far greater justice.
