I am saying AMR's rate of fire is too slow instead of Sniper Rifle being too fast. The fact that Gauss shoots faster, more powerful and lighter than AMR makes it bad.
The current Fallout sniper rifle is a semi-automatic instead of bolt-action; that means game balance aside it should able to fire faster then all level-action rifles in game. ATM the sniper rifle only have half if not lower RoF than the level-action rifles, and as fast as the frigging bolt-action Varmint rifle.
Again, Sniper Rifle being crowned king in NV simply because it have a ridiculous crit multiplier which evaluated it to do double damage *all* the time. Once that's gone any more complain about sniper rifle being too powerful is like saying why do you have to pay fines for speeding.
Sniper rifles having a x5 crit multiplier is probably an oversight from converting the Fallout 3 weapons to FONV, as almost all other firearms have been reduced to 1-1.25% (with the exception of Ratslayer and the LE BB Gun). So the proposed patch change is more like a bugfix than a nerf.
I am also not sure if lever-action rifles should be the standard on which to balance RoF, because they shoot much faster than they did in Fallout 3 whereas most of the other weapons either stayed the same or were nerfed. I admit that balance is a bit tricky since many of the new semi-auto weapons are also blazing fast (like the 'riot' shotgun) and many of the old weapons no longer have the 'sticky trigger' delays that prevented them from achieving maximum RoF in Fallout 3 (energy weapons especially).
In Fallout 3, lever-action designs like Lincoln's Repeater, Blackwater and the BB Gun had a firing animation where the player braces the gun across his body to cycle it after each shot, similar to the bolt-action hunting rifle. This resulted in a slow RoF and threw your sights off. Thus although the weapons were ridiculously powerful per shot (I had no idea that a .44 blackpowder cartridge does more damage than superheated plasma), they had a lower overall DPS than the semi-autos and machineguns.
In FONV, new and faster firing animations were introduced for lever-actions and pump-actions that no longer shift your aim between shots. Functionally, such weapons are now semi-auto, shooting fast and without the interruptions associated with manual operation. But this apparently was not enough to do justice to such badass weapons (Winchester lever-actions, for example, can supposedly shoot 120 rpm), so the animation multipliers were tweaked in GECK to make them shoot even faster. But they still do massive damage per shot, which is further increased by 25% with a low-level perk. Ouch. Cowboys are badass.
The Gauss Rifle is not as fast as it appears because it has a long and cumbersome reload animation after each shot, making it worse than the AMR.
