I've said it before and I'll keep saying it until I'm blue in the face: Dexterity is way too fucking overbudgeted in 5e. It was bad enough in 3.5e, but at least there you didn't also get to add your Dex bonus to damage.
This all just a symptom of a deeper structural issue, though. Since everybody uses either standard array or point buy, and therefore can choose precisely how to distribute their stats, optimization becomes mandatory instead of just being a "nice to have" thing. Back when rolling all your stats (or worse, rolling them in order) was the norm and you had to adjust your build to your stats and not the other way around, you compensated for any low stat with gear instead. But with 5e's attunement system (which in itself is not bad, since it helps curb some of the magical item hoarding that was rampant in 3.5e), your power is now usually squarely centered on your character's stats and class features so that Amulet of Health is taking the space of a Robe of the Archmage.
No system is perfect, of course. AD&D was a wonky-ass system in places. But I admit I've been getting tired of 5e's bullshit, and I've played enough 3.5e that I really don't feel like going back to it either.
