Not at all, but it can and does come to the detriment of DMs due to missing the potential of a fleshed-out game. The default play style has changed, and there’s nothing wrong with wanting it to be better/different or at least provided with solid variant rules to tailor it to different desires. The default playstyle was different before, and now it’s something else. Designers could’ve just as easily retained the older playstyle and provide variants for lighter play, more social mechanics, less death, etc. But they didn’t. They threw it away and offered very little to replace it. That’s all this comes down to across all legacy DMs who miss the older style, IMO.
Sure, we can all play older versions, but we don’t want to be left in the dust. We want the new shiny material, but also to be supported in our varying playstyles. If the game was more challenging across tiers - exploration and combat, what stops you from just making it easier? Why is it folks that want it more challenging that are in the wrong? I’m not saying your playstyle is wrong at all, but that there should be (and can be) room for all of ours.
