For me it's sticking with the full length stock and actually making it a bit longer. In a world where body armor was becoming the increasing norm that should have been enough to justify an adjustable stock. Internet weirdos are always like "lmao manlet" when you mention this but making a service rifle more ergonomically flexible is a good thing, and you look at stuff like Marines in Iraq regularly putting the rifle over the top of their shoulder and it vindicates that this was a bad call.
The second worse thing is the burst and not even because burst suck but because it makes the semi auto worse. It would have literally been better to make the rifle semi auto only with a decent and consistent trigger than to stuff in a burst feature everyone hates.
The rest of the changes are meh. The barrel and sights changes were kinda stupid but don't really affect anything in practicality. The A2 grip nub sucks but wrapping some grip tape fixes it so whatever.
In detail the M16A2 was a misstep in iteration but it's not like it was so bad it actually flipped any battles
