Traits are random so odds are this type of combo will happen just make him Gov of a growth penalized percussor world so the penalty is almost negated, though I hope it is +30% then - 50% rather than the reverse.

It seems to me that, if a leader is going to have an impact on growth, there should be one number stating that impact.  I find it hard to understand how you can justify having 2 numbers affecting growth.  What about 3? 4? 5?

I understand that the game is probably assigning traits randomly, but it should not be too difficult to not select more than one from any single category.  For example, it is not difficult to write code to randomly select some number of cards from a deck without duplicating any of the cards.

I think the only thing that makes this complicated is that it might be unknown how the math will work on it. Will the 10% only apply to the base or will it apply before or after the 20% is added into the equation. I'm not saying that it's bad to have multiples of the same trait type, only that it may be confusing for players on how it's calculated. Even more so if for some reason one was a positive and one was a negative trait.
