yes you are right about the last part being the most obvious, he shot the damn wall 3 times trying to get him (HELLO RED FLAG!). I sniped against him and I could already tell that he was. I am 100% sure he was using them. The timing of coming out, look for the enemy sniper, and put the dot right on him was way to fast. There was some points I couldn't even react. Soon as he came out, I could see the red laser right on me every time instantly and I moved around a lot on the battlements. That does not happen as often as it did without wallhacks. But I did have a 1:2 kill death ratio against him
