[@Crusader Lord] Questions are fine. Better to ask than to not ask.

1: I'm actually not too picky about natives or non-native character ratios at this point. There should be objectively more natives anyway, being that this is their world.

2: I go by a case by case basis, and it depends on what you want to do with your character. Genuinely speaking, your "average" score should be around the C level, but depending on what you want to do with the character, I would let you start with a higher or lower average depending on your character. Like I made Famished drop his score to D/D because he wanted to start with two elements. Though if your character was a paraplegic, we could justify making them magically gifted as a trade off for their lack of movement. But also keep in mind that the weaker a character is, the faster they scale up. so characters with low scores are most likely going to be the first ones to acquire authorities or other powers before everyone else. 

I'm a bit less restrictive when it comes to natives, but they don't start with return by death. I'm okay with most stuff as long as it doesn't go too far above the current power scale. But again, weaker natives will get cool stuff faster. But it's a bit harder to really balance natives because there are factors like their race, how wealthy they are, if they're going to help or oppose the non-natives, etc.
