Guns need ammunition, and ammunition is scarce on the battlefield. Much more important is the reloading/recharging bit. That, and combat in confined quarters might lead to situations where a longarm isn't ready or not of much use. Sidearms usually offer rather limited offensive capability, especially when facing body armor.
The U.S. military isn't huge on bayonets these days, despite the limits on how much ammo a given soldier can carry-- possibly in part because a given soldier can carry a fair bit. And that's with modern weapons. As for close quarters, a semi-automatic shotgun tends to beat a sword, and can be loaded with all manner of entertaining things. And then you've got the SMG.
Flashbangs for eyes and ears, frag grenades for when everybody must die, door charges for flattening the armored dude in the hall AS you make your big entrance....
A piercing thrust has no advantage you don't get from a gun, only with a shorter reach. A slash bites in confined spaces unless you can ignore things like walls-- and if you can ignore things like walls, the walls can't ignore you and you're apt to end up with a building on your fool cranium.
Ah-- and a sword's wall punch capability is limited by the length of your arm. Not so an LMG or similar toy.
Nope. Not buying it.
The effectiveness relies mainly on the setting.
Now you're talking sense.
Medieval knights were so valuable because they could afford their costly suit of armors, which stopped most weapons. The arms race invented many devious and less devious weapons that were a threat to heavily armored combatants.
None of which were fully automatic.
Or semi, even.
In the context of EVE's setting it's difficult to judge whether it's possible to produce and wear practical body armor that can reliably stop most SOTA projectiles (broadly speaking) or not. The Dust equipment seems to indicate that to some extent.
In which respect, it indicates that armor is distinctly permeable.
While Dust mercenaries can instantly clone and rejoin a battle, cyberknights might rely on heavy ( and expensive ) body augmentations that, for example, allows wearing much thicker and heavier body armor.
Beg to differ. DUST soldiers wear powered exoskeletons, according to the dev blogs on weapons.
There's bound to be a point where it's more economical to reclone and refit a DUSTer than to invest into maximum protection. After all the soldier doesn't care about dying, as long as he's equipped good enough to fulfill his objectives.
... which he is much less likely to do if he keeps dying.
I'd view it more as a cross between Shadowrun and W40k, the whole cyberknighting business.
I might consider the Shadowrun aspect (it's where I got the Dikote, TM, reference) but not at the expense of guns. Bear in mind also that Shadowrun's guns aren't too much more advanced than ours, smartlinks and flechette ammo aside.
Warhammer 40k, however? Nnnnnnno. That is a setting where badass technology has proliferated, then languished as people forgot the principles on which it worked. This is, IIRC, the setting explanation for why their guns are huge, permanently low on ammo, and do less damage than the little ones in real life.
Also, it's about as "noir" as an all-Valkyrie orchestra playing Wagner, with Thor on the cymbals.
As a genre, noir does many things, but over-the-top is not really one of them.
