There are a bunch of choices for custom factions which I personally do not favour. It seems to me that they are dramatically underpowered. I have listed them along with a suggested buff:
- Adepts (add +10% mana to all towns)
- Warriors (add +1 attack to all troops)
- Slave Lord (is OK, but counts as 2 picks, should be 1)
- Betrayers (same, should be 1 pick)
- Civics (add +10% Gildar in all towns)
This would make all picks a little bit more balanced.
