Just because one doesn't notice something or personally care about it, that doesn't mean it didn't exist or that others didn't care about it. Gygax and others talked about game balance (written rules and DM rulings) many times during the AD&D years. He even talked about balance in AD&D in recent years on this forum:

But we were young, (what? 15 years old? Younger?), and didn't care about game design theory.
I'd bet dollars to donuts, that if you ask a 15 year old new D&D player today about game balance, they don't notice or think about it any more than we did 30 years ago. It's not something that just recently came into being; it's something that we just recently came to think about.

Not only did it come up in the 80s and 90s (I started gaming in about 86), we were having pretty much the same argument about it as I recall. Back then people argued about whether balancing a wizard over the length of his entire career was a good or bad idea (weak to start, but powerful in the end), as they do today. I remember balance debates coming up all the time. As long as someone at the table could say "this sucks" because they felt outshined you would have these discussions. The only difference is the discussions were mostly real table conversations, you didn't have this massive online medium for arguing about the game with total strangers.
