Agamon
Adventurer
Doesn't this just beg the question? There is no corresponding differential between adventuring/non-adventuring elves, dwarves, and halflings.
Who's to say non-adventuring demihumans get the ability bonuses of PCs?
But I'm just saying that the problem, some say, is that it screws with the human average, making human somehow super human. But it doesn't, it only affects a very small percentage of the population. Adventurers are a cut above.
Now, let's assume that everyone in the world does get PC bonuses (that's very 3.x in thinking, but let's roll with that for argument's sake). The average of 3d6 is 10.5. If there's an entry for Human in the MM, it won't have stats that say 11.5. I guess the question is, if it's 12, then yeah, humans are better than they were before. While this is a quibble I have no problem with, there are apparently people who do, so you may have to house rule. If it's 11, then it really isn't any different than before.
