Less experience with FPS games-- Bad aim, bad tactics, bad understanding of the mechanics, the interface isn't really helpful for learning stuff unless you're actively checking out videos and outside advice, and the feedback loop is really, really long to actually "practice" any individual core competency from scratch.
my best advice is to start playing more agro and landing in populated areas (military base, pachiki, crates, apts, school, etc)! it'll help you get your aim down and get more comfortable killing other players.
My tactic is to try to land in a section like this, and secure a certain area. I land in pachinki, i try to secure a section of about 4 or 5 buildings, loot them, then either stay depending on activity, or move and look for others or get to the circle. If i land on apts, I land on one with a roof entrance, loot the building, and control it as there is bound to be another player who tries to enter.
The more comfortable you get with engagements, the better you'll be. I sometimes stick to myself and go to less populated areas when I really want to play more relaxed, but I did that so many times and for so long that I wasn't getting any better. Just last week I won two solos and i generally place top 10. Once i changed up my gameplay i got much better at killing and surviving.
The great thing about an agro start is that you didn't spend the last 20 minutes looting just to get killed. You'll spend maybe 5 minutes looting and either kill some players and go on to last a while, or die right away with really nothing lost, but that you gained some gameplay experience.
This is all so wordy and I apologize but I hope my point came out okay.
I managed to get chicken dinner by myself, bless.
i really need to go for more crates. I've only gotten the ghillie suite once because me and a friend dropped to the left of military base, took a boat to the bottom, and ran north and a crate dropped right on us perfectly. he took the awp i took the suite, but since then I've never even seen another, let alone am ballsy enough to hit crates, as they tend to drop in some bad spots.
