Ok so maybe that is a little overpowered, but the new fairy level Glossy at 58 pop/sq doesn't even beat a fairy residence.I can't speak to most of the buildings, but my glossy gardens (won in fairies) are 95.3 Pop and Culture per square, while my Wood elf residences (2 chapters later) are maxed at 100 pop, and are using 39.5 culture per square. Notably superior after 2 full chapters
Granted it's only 5% less pop than a residence and gives culture instead of taking it, but it gives no coins, and next chapter is 13% worse than a res.
Even nastier is the Dwarf chapter Glossy: It starts off as 13% less pop than a residence, and drops to 26% less next chapter.
If you split the difference (OLD pop + NEW pop)/2, this is what you would get
Making a chapter 8 Glossy give 10% less than the old chapter 6 Glossy is a two-handed swing from behind with the nerfbat after a running start. Far too harsh.
Another way to look at it:
If you upgraded your Glossy that you won in chapter 6 up to chapter 8, you would still have negative pop! Where's the incentive to pay diamonds for that?
