Buffing gimmicks and introducing stronger mobs to match them doesn't work, it only makes early content ever more irrelevant. It only enlarges the gap abyss between what is relevant and what isn't in the game.
Nerfing was never the problem, it was the only thing that could keep power and damage scalling linear, or better, at predictable levels. Enough devs have made the mistake of introducing ever stronger loot on games designed with a different scale in mind, I honestly hoped the gaming industry would have understood it... balance is a holy grail, it stands for long time player engagement
