I wish you all the bad things in life.
Just a basic normalized distribution tells you that if you increase the population size, you will be diluting of the mean because we are not adding top talent on the other end. If they were there to add, they would already be in the league. Not like there are 20 1Cs over in Europe or the KHL that can't get an NHL deal. Instead, you're adding several AHL/AAAA players. So yeah, overall weaker. I do not agree with your premise.
Not realy. Provided that the player pool increases proportionally you will not be diluting the mean.
This obviously ebbs and flows as you add teams.
