You rarely see archaic weapon designs be criticized not just because sword autists are a way smaller niche than gun autists but you also have to take into account how far we're removed from the type of warfare where you smack someone in the head with an axe while wearing heavy as fuck armor, people just don't realize how light even most "heavy" melee weapons are, a zweihänder usually weighs just 2.3-3.2 kilograms (5-7 pounds). There are ceremonial zweihänders that are quite a bit heavier than that but that's because they're not meant for battlefield use. It's one thing to carry something, it's something completely different to actually swing that thing, in games though you often find big boy swords weighing 20 pounds and you'd imagine if you showed Joe Average some big two-handed sword they'd think that it weighs about as much.
And that's just raw weight, I could go on for hours about the importance of balancing that weight and how fantasy swords would be unbalanced and therefore unusable but I just don't have the will to do it given how pointless it is.
