Thanks for the feedback but I'll keep the reply short for the sake of productivity. Firstly, a minor note, daisy is offered 5k in more recent version.
Now onto suggestions.
1. Pass, you can take traits and trainer classes to increase trained slave number, or use subordinates as secondary trainers.
2. The reason why it was cut down is to make managing less tedious on the mid-lategame as well as make it less intimidating initially. While I can consider brining back some of social skill mechanics I need some more coherent suggestions which won't damage that intention.
3. Current factor increase system is more of an afterthought and I also wouldn't mind revisiting it eventually but in a more faithful game vision (hard mode) only growth factor upgrade is really an option.
