I vented about this on Reddit so I'm just going to paste that here:
Over the past few years movement shooters have surged in popularity, which was exciting, but Ive found myself unhappy with how these games end up turning out. I'm going to be speaking very broadly and not all of these issues are going to apply to every recently released movement shooter.
1. Lack of mouse involvement in movement tech.
The mouse is a really interesting input device. It's extremely granular, precise, and moving it around has a very kinetic feel that separates it from buttons or analog sticks. I have boomery tastes in the sense that I prefer strafe jumping/bunnyhopping over sliding and wall running, but I'm certain I wouldn't feel that way if those sorts of mechanics involved more mouse usage. Sliding and wallrunning look cool and are way more intuitive to understand than bunnyhopping, but since that sort of movement is usually done by simply pressing a button at the right time, there really isn't any depth to the mechanic. I'd love to see a game where wall running requires you to move your mouse in a certain manner kinda like surfing in counter strike. I think it would be really cool if you could wall run or faster/longer as you get better at moving your mouse at the right rate against the wall. I like that more shooters are trying to implement more movement options, but I wish they were just a little deeper and rewarded you for practicing them and not just learning of their existence, and I think getting more mouse action involved would be the best way to facilitate that.
2. Assault rifles.
I think a lot of movement shooters shoot themselves in the foot by making the weapons heavily tracking oriented. Having lots of way to juke opponents feels way more impactful when you're using those techniques to throw off single shot weapons and projectiles. When I dodge someone's shot I feel great, but when my movement just makes somebody hit a lower percentage of their clip I honestly can't even really tell. Back to my first point, having more single fire weapons would also give designers more room to implement more mouse usage in movement tech as there would be time between shots for players to use their mouse for things besides aiming. One of the most underrated appreciated aspects of team fortress 2 is how good it feels to move your mouse to airstrafe away from a rocket only to immediately flick back onto the enemy to shoot them with your shotgun. There's a natural trade off between movement and aim that can be overcome with skill, which makes the aiming aspect of the game feel a lot more expressive than just holding your crosshair on the enemy for as long as possible.
