I watched till 1:30 minute of that video, what did you post proof of? Is it that quickscoping is ridiculous in Black Ops 2? Not at all, the dude tried to quickscope around 10 times and only succeded once (based on the minute and 30 seconds that I watched), You're proving my point breh. Is it that shotguns have AR range? Not at all, the shotguns kill at close range because that's their purpose. You're the one that's spewing bullshyt.
- Treyarch made Black Ops 2 very balanced. There was some issues in the beginning but that's the be expected. Everything in terms of gun/equipment/etc was patched. There was no shotgun with AR range in Black Ops 2. They all, except for the KSG had very short ranges. KSG had decent range, but you had to be really good with your aim and even then you needed more than one shot to kill at a decent range. Pistols were balanced. Kap-40 was a bit over-powered in the beginning, but it got nerfed.
- Treyarch balanced quickscoping. It was and still is difficult to quickscope in Black Ops 2. You can't really quickscope and if you try, you will get steam-rolled.
- The game had lag and lag comp. issues, but it got much better with the patches. Run a game on multiplayer right now and 8-9/10 games will run smooth. Run a game on Leauge Play (which has dedicated servers) and the game runs even smoother and more lag-free.
