You keep bringing up gameplay, but did you consider that forced ADS at every point might actually be a bad game mechanic? It slows down gameplay and completely eliminates a major mechanic (movement) from the equation while you are shooting.
I never said aiming properly should have to be done every single time you shoot.
I just said that point-shooting shouldn't replace actually aiming 100% of the time.
IE unless you're REALLY just trying to show off, you shouldn't be neglecting your sights if the enemy is
farther away. Point shooting should be reserved for when something is so close that aiming doesn't matter, or you're just pegging a clot in the chest because "Eh, **** it"
If point shooting is always 100% accurate to a specific point on the screen like KF1, then like KF1 playing sharp will just be point-and-click and give too much reward for too little difficulty.
Also do you think sharp should be totally useless against anything that's not a FP? Sounds mighty fun just idling at a corner waiting for FPs to spawn. In KF1 you can make yourself useful as a sharp at all times. Perhaps too useful sometimes, but at least killing biggies is not everything you can do.
Every time I've tried playing a Hell On Earth game in KF1, that's EXACTLY what was happened. The Sharp would hide in a corner and never shoot unless they saw a scrake or FP. It was boring.
And no, I think Sharpshooter should shoot at ALL priority targets. Husks and Sirens die easily enough, for example, but if you can kill one in a single, quick shot, you can save your teammates a little heartache.
In difficulties below Hell On Earth, however, the Sharps kill EVERYTHING. Every clot and crawler that walks through the door, because they can do that easily with a handgun (or just waste all their rifle ammo and take all the ammo boxes) There are a number of classes in KF1 that are really good against certain enemies or in certain situations, but Sharps were good against everything in every situation. That takes away a lot of fun for other classes playing WITH Sharps, because the Sharps step on their toes when it should be their chance to actually get to do something.
Now that Sharps aren't good with handguns and recoil is going to delay how fast they can point-shoot multiple times in short order, it's going to be much harder for Sharps to efficiently and effectively deal with, say... a big horde of crawlers/clots that sneaks up on them. So this time they might actually say, "Alright I'll play my role of sniping out priority targets, and let you guys play your roles and not step on your toes so much. And if you watch my back so I can stand here and not have to run around a lot, I can get this unexplained bonus for standing still"
KF1 actually simulates point shooting pretty well. You can get almost as accurate as ADS at closer ranges when you practice enough, just as it should be. I don't see what's the problem here.
See, it's not the closer ranges where "100% point shooting accuracy to center of screen" becomes a problem. At closer ranges, you don't need to be 100% accurate anyways. You can be like 95% accurate and still reasonably kill the thing in the same room as you.
Beyond the range where anyone should reasonably be TRYING to point-shoot at a target is where it becomes a problem to have 100% accuracy to the center of the screen, because that's the only time you WOULD be bothering to use the sights/scope anyways.
