Right now structures are a trap since troops should be able to handle early foes without needing them, and later on you want as much space for your 80 mob army as possible and some structures get bugged and are unremoveable. I got very lucky and started with a +8 hp, +1 attack orc, which made breeding a quality army much easier once those stats had started to cycle through oni and into my breeders. stopped at day 20, with +10hp, +1attack breeders, +12 hp on my orcs thanks to a lucky purple, but still only +1 attack. currently doing a side breeding operation with a couple of +3 attack girls to try and get those stats into my general breeding pool. purple stat boosts/mutations seem to be much rarer this version, or maybe i just got unlucky with only seeing 6 in 20 days, with only 1 being useful.
pc, gobs and orcs get unique animations with regular girls, spellblades and sisters, plus the 2 combinations in the field, for those who haven't been keeping track.
This version feels like a step back, since we've lost traits, the ability to raid and the ability to send off girls for benefits, but hopefully we'll be getting most of that back soon. I'm mourning the drop in breeding/eugenics potential, as i have a lot of fun breeding the best statblock in previous versions and their last game. traits are going to come back in later updates, hopefully raiding too since being able to hunt for useful traits and stats is a boon.
Biggest gripe would be the lack of automation for birthing, as it means you can't really make use of all the dungeon space without going mad managing it all. I capped out at 6 orc and 6 gob breeders, plus 4 oni/shortstacks, and even that was a bit much, and i had tons of free space after the last extension upgrade.
Second biggest gripe would be the rng on the pc/monmusu breeding. even my +10 hp oni kept giving me crappy statted kids 95% of the time, I wish they'd change the mechanics of how pc breeding specifically works so that the kids tend to be much closer to the mothers statline, right now fishing for good offspring to cycle into your monster breeders takes forever. automation for birthing would help a bit, but you still would need to manually move the pc around your monmusu breeders.
