Someone made a good point that the reason scorched earth isn't a red AI is because when there is only one of them, it isn't all that bad. However, if both of them are scorched earth, then it be becomes worse than even crafty spire, technologist, or "the core" AIs.
Also, has the "try to avoid repeated AI types" logic take into consideration the now up to two types per AI player?
Also, does having one of the types be "vanilla" basically act the same as if there was no secondary type?
