I will disagree, on pulling above 1kd people are cheating, myself yea i don't even consider im good, im at 1.7, there are games where ill go and dominate, and there are games where ill struggle to keep 1kd. And mostly i play Assault class.
I have squad mates with 3+ Kd's (we all played older BF titles together and allot of Counterstrike)
Sometimes i rush objectives, sometimes i play slow and methodical.
In games i have noticed People don't use tools they have, or counter those said tools.(Drones, Movement sensors, UAV's, and most important ones Sound and Minimap) im the guy shooting down enemy drones, looking for Movement sensors on Points. If my team gives me that information, I prefire corners or throw few cheeky grenades. If im in tight point i tend to move slower so less sound when gunfight starts there is no point in moving slow anymore.
Sadly game design made all other muzzle devices obsolete, only flash hiders and silencers are viable to use if you don't use one of those you get auto spotted every time you shoot.
in countless games i have seen enemy drone hovering 5m above point and no one is even considering to shoot it down, what dose enemy team sees in minimap/map location of everyone on that point, snipers sees doritos trough bushes and trees, and because of said doritos its way faster target recognition for their infantry.
Motion sensor dose the same thing only in smaller area and detects only movement.
And Yes you can shoot down UAV's
Allot of snipers still use broken RengeFinder its slow its clunky up to 200m its not needed at all, im not using one on most of my sniper builds, only super long range one i use it 500+m
at least in Multiplayer part i cant say i have encountered any super suspicious players, only bug abusers(No sniper glint, roof campers in breakthrough.)
RedSec on the other hand, me and my squad we have won countless games, but as its free to play and allot of shady people.
P.S. As i stated in opening i don't consider myself a good player because i know there are better players than me tactically and mechanically, for example my squad mate he shoots 800m snipers shots without rangefinder he understands how much he needs to lead the shot just from his scope, and how fast he can switch in between targets in close situations, hes an excellent marksman, but he loses to me in medium range, that's my strong suite, but as overall package he's a better player, i guess accepting that comes with experience and age.
