Vermintide has some of the best first person melee combat in any game I've played, second only to Mordhau objectively, but way more fun than that sweatfest subjectively. (Mount and Blade has quad directional attacks and blocking, woopee, who gives a shit. It was impressive for its time, not anymore.)
Anyone who says that Vermintide has bad melee combat, explain yourselves now. Allow someone who used to solo Legend difficulty and has every red item and weapon he desires to break it down for you plebeians. VT combat is immersive, brutal, weighty, and very intricate. At any point during combat you will be manipulating enemy positioning, choosing whether to attack, charge attack, or block, when to dodge and where, when to expend stamina points and block or push, whether to attack or not out of that push, when to use your ults, when to quickly swap to your ranged weapon to snipe the disabling special unit closing in on you in between enemy attacks, which attacks to combo into, where to distribute the damage of each swing across the varied enemies included in the horde attacking you, et cetera et cetera.
If you bring a light weapon like a dagger or a one handed axe to try and cleave through a crowd of enemies, your swing will stop midway as your weapon loses momentum and visually lodges itself into one of the enemies ganging up on you. Even heavy weapons experience the same problem with high enough enemy density, meaning you cannot just mash away without maneuvering the enemy horde into a favorable position for your attacks. Limbs and heads get severed or smashed depending on if you brought an edged or blunt weapon respectively, blood flies into your eyes and obscures your vision as you cleave through hordes of chaos and ratmen, the music is excellent and gets you in the appropriate mood, there's an unprecedented amount of dialogue and character building between the cast. Each career is fun in its own way and offers a unique playstyle, as well as between the characters themselves, besides the ranged careers which are easy, simple, and too boring. Being a new player and seeing the sheer size of a chaos horde charging up a hill or across a field towards you in an open map like Athel Yenlui or Against The Grain, or hearing the Norsca Chaos track kick in and a Spawn of Chaos barrel through an incoming horde towards you, will nearly certainly have you hyped up and ready to fight. You experience feelings from being a single human trying to survive a flood of adversaries all the way to a hero overcoming ridiculous odds all in one map assuming you don't die like a chump when push comes to shove.
In closing, VT melee combat is both mechanically deep and emotionally/aesthetically satisfying, compared to games like The Elder Scrolls where combat is stiff, animated locked, weightless, sterile, and devoid of skill. Unless someone can raise a good argument about why it's bad, I will continue to think that critics are either too bad to get past the beginning difficulty levels of the game where the game flow and weapon balance is completely off, or they just have bad taste and don't "get" it.
Vermintide has plenty of problems, which is why I still have a negative review of it on its store page despite almost having 900 hours played as of writing, but bad melee combat is not one of them. Going to day 1 purchase Darktide because it is just going to be Vermintide but 40k and that's exactly what I want from it.
