You are not alone. I've been playing Destiny intensively for 4 months now and I still pepper someone in the crucible and get killed by one or two shots from them. I'm 290 light with good armour rating. Sticking next to a team mate is fine but when you, or he, gets killed and re-spawn at some remote location, that's when you are a vulnerable lone target trying to get back into the fray. I've lost count of how many times I've been killed doing this. I'm now getting more success rushing in with a top end shot gun than standing off with a rifle, but my efforts still get me between 1 kill bad day and 12 kills good day results. Anyway, back to the one or two shot kill, I have an observation. Is it possible for someone to lower their light to 180 to get into lower level matchmaking, then raise their light back up to, say 295 with kick ass gear whilst in a crucible match. Could this explain the one or two shot kill with a scout rifle scenario ? Whatever the case, it seems there are many guys out there who can make their crosshairs stick to your head like hair gel, wish I could do it.
