Tell me about it. I almost smashed my game yesterday! I shot this person 5 times while they were running and it seemed like nothing was registering! Then they ran back and got 2 shots in me and died. Yeah sure whatever. But I don't get much hit markers and die enough to be enraged but it does suck when every shot u shoot does not kill em.
Accuracy and gun power matter. Certain weapons just aren't as powerful, especially from range. I find that the Majority of hit markers I get weren't clean, accurate shots. The rest are a factor of the weapon I am using. SMG from long range in HC will garner you hit markers, a lot.
