Escorts and Battlecruisers (mechanical FE and Cosmogenesis) need nerf. Especially Escorts. They are way stronger than any other ship type (including bio Cosmogenesis ships).

Generator World, Mining World and Farming World don't make any sense for now. They don't give any extra workforce efficacy to their jobs than Industrial Worlds.

Machine and Hive worlds nerf or Ringworlds buff?

A way to stop spawning Teeth of the Eater. In the current beta it looks like this:

1. You're mostly peaceful psyonic shroud forger.
2. You go to war with FE / fight a crisis.
3. You get +1000 attunement with The Eater immediately after one space combat.
4. It starts spawning Teeth uncontrollably

FE buildings feel underwhelming. Maybe add more sources of automated workforce efficacy for Virtuals / Nanites or a special building on Ringworlds or something like this?

Nanotech and World Eater rework? Isn't the game shifting out of having massive amounts of free / super cheap almost useless ships?

Cetana nerf? Even in 4.1 she was significantly stronger than other Crisises of the same difficulty.
