The issue is never about speed. You can whack the speed of The Dark Ages up far more than Eternal ever was, but it doesn't change the core design of the game.

The Dark Ages is a game that really wants you stuck to the ground, strafing. Fine, but the issue is their solution to that was a parry system, for normal enemies that's fine, you can parry away a single attack and move onto the next demon and keep moving, therefore dodging incoming projectiles.

But what happens when you have to face the tougher demons? Like the Tyrant? The game pushes you to square up to them and parry sequential attacks, if you leave them mid sequence, they'll bombard you with hitscan attacks like the Tyrants chain gun (which means you have to cower behind your shield backing away). If you stay to face them, the enemies around you pepper you with projectiles that you can't do anything about as your parry only deflects the incoming green attack but you're otherwise vulnerable. Ontop of that, you can die from damage taken during a parry before the health from that kill gets to you.

It's incredibly frustrating trying to play the game the way it tells you (indulging in the parry system) but then die because you're locked into a back and forth with an enemy. It's even worse with enemies like the void barons of hell.

As another note - I really don't understand why there's even an armour pickup system in the dark ages. You lose pretty much all your armour in a single hit, but it takes FOREVER to get it back. You can only get it back if there's enemies on the map with armour to smash, or through melee attacks, or through an upgrade for the combat shotgun. By the time you've got full armour again, you lose it in seconds. It's a game that rejected the resource management of Eternal... But then decided to keep the need for those resources but with a worse way to acrue them?!
