I've only had a couple of games that approach that level of total kills. Every once in a while the stars align and you feel like every one of your shots hits it's mark. My highest scores always come from the medic class - love the repeating rifles and I am a reviving fool.
And apparently hunkering down in a foxhole makes you invisible
This is a real thing.
My first experience was on Empires Edge at point D. I'm hunkering in a crater at point D surrounded by the opposition and I get about 6 kills. Move on and the same thing happens at point C. Chaos all around me, I'm in a crater getting kills.
My first thought was maybe it's an aspect of design. I have my brightness settings such that everything is visible without ruining the visual appeal of the game, yet it seems there are areas--corners in buildings, a spot in the rubble--where one can crouch and blend in with the blackness. Like at point B on Amien, there is a blown out building with smoke rising from it and you can't see through the smoke. If you sit there people will not see you. So, I thought maybe sitting in craters was something like that.
Another possibility was the people I was playing with were not very good. Because I'm not very good, and this should not be happening.
Then I tried it on some other maps. Suez point D, right? People will definitely find me here right? Not so. I had the same outcome. Not at your level because I'm just not that good, but I would get 5-6 kills and capture the flag before hearing Captain Miller in my head yelling "Displace!" knowing the guys I took out are coming back for me.
I've had similar success on other maps and I've come to the conclusion that it is the pace of the game and where the majority of the opposition is attacking from which is standing up, running at you, or lying down in the distance that grabs people's attention and focus.
Then again, maybe I'm just going against a lot of inept players.
I haven't seen it yet. Seems silly they don't have it at least on conquest or other non-ops. I can see why they don't have it on Ops cause it's just Victory/Defeat, but it would be nice to see like total K/D or sectors taken/defended.
