Just did 75 matches back to back for the Redrix quest. What you're describing is a symptom of an overarchign problem that is the cause of a lot of crucible problems. Latency. As you know Bungie uses Peer to Peer connection, which is awfull and the only reason companies would use this is to save money, which I don't think is bad. What not everyone knows is that there is a second system on top of that. I don't fully understand it but basically what it does is make sure that your experience stays smooth. (No rubberbanding and input lag). However this does NOT fix bad latency. If you host has a 1000 ping you will still have a full second disadvantage. because of the horrible connection system PVP feels incredibly inconsistent. TTK varies, getting shot through wall,... I've had matches where I was standing against an enemy player, we both shot our shotguns he walks away with half a health bar. I checked, all pellets of my shotgun hit him. No buffs, nothing. This is purely due to latency. Essentially what happens (or I think at least) is that due to the latency in actuality I was standing further away, which meant my shotgun does less damage, but on my screen everything seems fine. I've hit people with in the head and they walk away, i've hit people with only the blast radius and they get instakilled. You'll probably also have experienced some people shooting nyou with a Grenade launcher point blank and not getting damage. That's, again, due to latency. If Bungie would invest in a better connection system (I.E Dedicated servers) crucible would be a lot more enjoyable. I don't blame them for not doing it, servers are expensive. Nevertheless, the crucible experience sucks due to immense inconsistencies. I enjoy it the majority of the time but I fully understand why a lot of people hate it.

One of the changes coming Tuesday will affect range and damage falloff on a variety of weapon classes.

Duke has high range, so does ace. Get good.
