Some recent forum posts have revealed Treyarch's plans to fine tune the sniper file and knife attacks, hoping to address complaints that sniper rifles are too weak, and knife lunge is too powerful. The changes will hit in the next Call of Duty: Black Ops update, and you can read about them below.
These are the planned changes for sniper rifles, as announced by Treyarch developer Vahn on the Call of Duty: Black Ops forums :
Treyarch caused some controversy when they removed the ability to quickscope with a sniper rifle, and admit that it has weakened the weapon as a choice. Vahn says “we stopped Quick Scoping for the most part. We mostly invalidated a sniper winning a battle with a Shotgun or SMG at close range. This was the goal. However, this has come at a pretty large cost to sniping in general.” Beyond the changes listed above, there are more tweaks planned to fine tune the sway of the scope when aiming, but these will come in later updates.
As for the knife , Vahn had this to say.
“We've made some changes to the knife tunables that will be available in the next game update.
We are not currently planning to remove the lunge, make the knife a 2 hit kill in the front, or make you pull it out to use it. These are all good community suggestions that are appropriate for a future game that has a Barebones or Pure version.
That said, after thinking about a bit more, it seemed reasonable that we could do additional (and larger) experiments on the lunge and swipe ranges and see how they play out.”
