Connectivity issues, yes, I play with a base 220ms lag, but that would explain one stomped to death OHK gunfight, not all of them from the same player. ...right ?
I technically run operations I need perks, AKA total random ones; HOWEVER, my favorite build from when I was on PC is: Ready Up, Slight of Hand, Takedown, Dead Silence and Hardline (removing the lethal, usually). SA-805 with Silencer and Red Dot (tho here in Xbox it have proven to be useless, I'm currently using an AK with same attachments), .44 Magnum with Tactical Knife, Concussion. Assault Com Sat, Dog, Battle Hind (tho I never throw the Hind, I have it just in case I actually get the streak), else I go Support Com Sat, MAAWS and Squadmate.
My typical play style is checking choke points (usually transited areas) where none of my teammates are nearby; wait (camp) there for a few, name it "any sound within 30 seconds" and if there's nothing there, I move to the next closest one, always carefully crouched, with Dead Silence and hugging to walls or anything that covers me or doesn't leave me in the mid open. I also try to don't repeat my pattern (like walking the map clockwise) but to take a different path each time and avoid places where more than one teammate was killed. This works kinda fine since I tend to flank most of the time and catch enemies from unexpected locations and allows me not to engage if I know I won't make it. However this keeps me getting into choke points filed with enemies I didn't notice due to no Com Sats or lack of attention on the rest of the team's guns fire (my bad there, but my TV is huge and the map is kinda small and I need to take out my eyes from the center of the screen to watch it); I also get killed by campers already in the choke points (not 'coz I don't know the camping spots but more like a "camper is expecting me, I'm not expecting a camper" ) and I also keep getting sniped while sprinting thru locations I have no other way to cross.
This whole stuff works fine as a field covert ops catching enemies off guard and gets me a 1.2+ kill ratio without much issue; but lately I'm starting to have issues dealing with people (ex: they are sprinting and I cannot land the third mark before they get behind cover; roamers I encounter all of a sudden win the gunfight without much issues; people somehow knowing I'm coming from that way; etc.) I don't really have much issues with stuff like IEDs or dogs, but unseen Sentries and IMSs usually mean death. I'm not exactly a roamer nor a camper, I'm more of a short term camper which switches locations a lot.
Tips appreciated ^_^
