As one of the trait-editing advocates, I'll simply say that adjusting from Mobile to Balanced simply fixes whatever EA broke in the patch that caused QBs to scramble at twice the old rate. Balanced simply plays as Mobile used to, so Balanced trait guys will run on you and force you to do all the "learning/adjusting/trying hard" that you valorize above. I just played Rogers, who is Balanced, and he took off on me 9x. I had to spy him almost every play at the end of the game.
So I think your characterization of the fix is a bit reductive and not entirely charitable. Granted, editing traits is not for everyone, as it's a little extra work, but it's not like it makes for lazy gaming, either. Just sayin'.
