An idea I had:
Keep the Fighter's BAB progression, or something like that, have some decent hit point progression, but keep AC mostly static, increasing minimally, throughout the game. Instead, make it so that for every 5 or 10 you beat the opponent's AC by, you roll the damage dice again and do extra damage.
Something like that may allow the progression to be significant, at least enough to be noticeable, but make it so that power level is overall "flatter". Weaker enemies still pose a threat and you stand a bit more of a chance against something that's higher level.
...I think.
