Shooting from shouldered wouldn´t be easier, as I said only the more straight looking first person weapon model would give you little more comfort in "sensing" where you are "aiming" at.
As I also mentioned I personally would prefer to have no hipped or shouldered, but instantly the aimed (which includes shouldered as well). And if I said faster aiming, I ment getting into the aimed position from the low ready position. IRL it is very fast (depends on the weapon you use), the difficulty is in the aiming itself (especially on longer ranges). This "difficulty" you have with the breath (and maybe handshake?) in INF and if you hold the right mose key, it takes a little time to have the sights really straight, as IRL. So I think INF got most things that are realistic and it works fine.
And I think in INF, if you run over a place where a "good" trained sniper player is waiting, you are dead, so it is all kinda realistic in INF.
In INF, if you play ucarefully, you get hurt and are slow`n`lame (leaked time of fun), so I think you, as player, are afraid enough of uncarefully playing, same as real soldier are afraid of risking their life.
@Famas:
Yes, A little problem we all know
I would prefer only the aimed position in INF, cuz why you should shoot unaimed IRL if you can aim fast? Lets see it from that direction.
I that case, some would disagree and would like to have shouldered, or hipped. And since INF doesn´t restrict players from things that are possible IRL, but not often used (such as shouldered, or hipped), It could be implemented in the game as options.
Not so good Suggestion:
One Idea I wouldn`t prefer is to be in low ready and aim with the "right mouse key", but shoulder the gun if you press the "left mouse key".
If you are in one of the modes, you use the left key to shoot, the right key to decativate, or hold breath.
You could be able to switch from shouldered directly to the aimed if you push the right mouse key double, or from aimed to shouldered, if you press the right key and instantly the left key.
But I would prefer to shoot with the firekey no matter if you aim, or low ready (as gal-z said), that would display the realism in INF`s manner and would force you to be more carefully with your weapon.
Good Suggestion:
The suggestion I would prerfer is, to have the low ready/aimed as standart, but you could be able to toggle with a special key the aiming modes (aimed/shouldered and maybe hipped if you want). With the right mouse key you would use the current aiming mode.
The current aiming mode would be displayed in the hud. Maybe the aimed mode would have green typo (color), the shouldered orange (as less accurate) and the hipped red typo (as even more inaccurate).
Maybe it would be good, to have this toggle on the "mousewheel up", "mousewheel down" stuff, cuz than you could toggle better between the 3 modes. If you aim a rifle, you could use the "mousewheel down" to unaim the rifle, but hold it to the shoulder (shouldered) and again wheel mouse down, to hip it (with all the 1st person animations). Using wheel up would shoulder the gun and than aim it again.
Using the wheel in low ready would just define the weapon aim mode you will have if you press the right mose key.
That would be awesome in using the acog assaultrifles. you could define with the mouse wheel your personal aiming position and could be able to use the rifle shouldered. From the shouldered you easily could be able to aim through the acog scope (using wheel up) and that would take even less time than to lift the weapon from low ready and aim the scope
.
If you choose the aimed mode (as me), for comfort sake you would just use the right mouse key as in actual INF to aim, or low ready the gun.
On that point I have to point out, that it is even in the hipped mode difficult to hold the rifle straight for a longer time without to get tired arms, so for realism sake, you would need the low ready position even if you hip the gun
