Not really seeing an increase in numbers in BECMI and 2e, save relative to OD&D.
For BECMI I was referring to OD&D. 2E saw the effects largely on the monster end of things. AD&D monsters were for the most part weak vs a party with high stats and lots of magic items. Check out Dragon magazine's tale of Lord Arrago vs an ancient red dragon.
2E PC's were much like 1E but giants, dragons, and some other monsters got a huge power boost. I think the monster design for 2E was influenced by the higher stat averages of most characters at the time. This is just speculation on my part. Any 2E development insiders around?
