Yesterday we played RO1 clanwar and it was obvioius that the weapons were much harder to handle when not deployed.
You didn't see people shooting from the stand in RO1 very often due to this. And so I think the weapon accuracy is in RO2 even in Classic mode still too high.
I think weapon accuracy (one way or another) needs to be drastically decreased. Currently fire and manoeuvre doesn't work because you can just pop out and shoot your opponent in the head at 300m, easy peasy. That's just superhuman, sure someone could shoot a head sized target at 300m but they would aim completely differently, they would let their arms sway (holding a rifle rock solidly causes shaking) a little and fire when it all lines up. This only happens a little in RO2.
Some games decrease accuracy using obviously artificial methods like cone of fire (BF is probably the most famous example of this), it increases the amount of movement you can do but is frustrating because there's no indication of this cone of fire, it just bends a perfectly good shot into a bad one.
RO Ost did it with huge sway and NO zoom, meaning a lot of pixel hunting but it also meant you wouldn't get hit at range. I ran into situations where me and an enemy spotted eachother at only 50 or 100m range but knew that if they tried to bring up their ironsights and got a shot off the other would already have run to cover, so we just ran by eachother. In Ro2 you just snap up the sights and go for the head, blegh.
Sight misalignment is a good way to indicate cone of fire (they're just two sides of the same thing really), and far less frustrating, but the player should be somewhat able to counteract it, so that there's a high skill cap and you can learn to use the gun better (by no means should improving rank make this misalignment go away, you should be getting better as a player not as a character). This, combined with slight jitter in some circumstances (holding breath for more than a few seconds should introduce a little jitter, and releasing your breath should cause quite a large sway, and possibly when completely out of stamina) and quite a bit more sway would allow highly skilled players to retain their accuracy, but force them to take a bit more time to aim a shot or risk being inaccurate.
All in all, I'd love a system that does not rely on luck, but may seem like it to a newcomer, a system that forces aiming to take time, to be hard, and to require a lot of skill to do. I understand that's a huge challenge to create but this is a shooter, and good shooting should be the emphasis.
