My biggest problems I run into are blindfiring being way too accurate, and the dead body glitch.
There is a glitch called the Airwalk. & if you've been around since Uncharted 2, you would know that there has been about 4 different ways to do it. The latest version, people call it, "Airwalk 4.0" It isn't done in multiplayer alot, in fact, I hardly run into it. But it could be a really easy to fix glitch. Basically, it's where you can literally float, horizontally, across anywhere you want. You have to go across some sort of ledge though. And if you are REALLY skilled, you can actually float vertically, and you can get outside of map. Which is pretty cheap to do.
There is also a glitch where you can sit on a plunder treasure, (or even a propane tank) blindfire, and it will cause you to rapidly spin, and if you spin fast enough, you can get outside of the map. It needs to be fixed. (I dont think it has been at least)
The last one is where you can sit on top of a plunder treasure, and it will float vertically, and you can get on rooftops, and out of map.
I wont tell you how to do them, but yeah. Its something that should be patched.
By the way, there is actually a way where you can PURPOSELY dead body glitch. (Usually, it just happens somehow) But there is a way where you can manually do it. That needs to be patched.
