I think that flashlights add a small challenge..
That's exactly why the flashlights are on semi-weak weapons, depending on the perk you're playing as. It adds a moment of weakness to your otherwise pretty strong arsenal of weapons (unless your firebug and short on ammo). It makes you risk firepower for sight. Unless you're commando, in which case you wouldn't need a flashlight. Just look at health bars.
i don't mind it as it currently is, although it is odd how only the shotgun gets a flashlight and the other perks don't.
I think it's because most other weapons are two handed. Flamethrower, LAW, Katana, Chainsaw, Axe, etc. Although I don't understand why they don't have a flashlight option for machete and knife. Especially the knife, seeing as how the flashlight's only available for weak to semi-weak weapons.
Really, I think the laser should have been on the SCAR, not the M14.
I second that. The achievement with the M14 pisses me off. Every time I play clot mut and try to get 25 headshots in a row, some ninja clot always sneaks in the moment I shoot another clot and I kill the ninja clot by shooting its arm off. Then the counter resets.
