There is no presentation of 'average'.See, this is where I end up losing the conversation. A lot of discussion about Racial ASIs is that they "encourage" archettypes. Like playing an Orc Barbarian. And then we seem to have two different view points that constantly shift.
Either playing an Orc Barbarian is more powerful than the average, and playing an Orc Warlock is average or Playing an Orc Warlock is weaker to represent a higher challenge and playing an Orc Barbarian is normal. No one ever seems to disagree on their relative position, but I've seen a lot of people put forth the idea that 16 is somehow more powerful than average when I find that position to not follow from the evidence we have.
What is my Class.
What is my builds Primary.
What are my desired secondary stats.
What optional rules do I get to use.
Many (most?) don't consider an average.
'I put my 15 in my Prime Stat, and my +2 as well.'
There's no thinking, no choice, no cost/restriction/balance.
You make the game as easy as possible for yourself.
Averages, are as meaningless as Balance.
