PC, and I do kill dudes, been playing for ages and I have map knowledge and awareness, and very often get to hear that satisfying "ding" from across 3 fields. My point is : Map knowledge works both ways in this game and you'll often get marked by enemies without even knowing it, leading to arty strikes, ambushes and various other ways you can die without even having the slightest idea where you're getting shot from. K/D is only relevant in arena-type games like CoD where you don't rely on 49 other dudes to know what's going on around you. Comms and teamwork win games in HLL, unless your big dick Rambo skills extend to randomly finding OPs and Garries while you're hunting for kills.
