Rank Skill Gap APAC

My peak is plat 3 and but my game sense is much better as i think. problem is i cannot go far because my reaction time and mechanics. when i get higher rank players they shoot before me. sometimes i only saw enemy and no time to react(even kill me by body shotting before i react). when i play in plat i loss 1v1 face to face most of the time. also my headshot percentage is high than 40% most of the time.
The teammates i found in my lobby is mostly don't have good game sense and also not even watch map. but kill enemies easily even body shooting.

what i can do to improve. please help

More often than not, if you feel like you don't have time to react it means your peeking or holding technique isn't ideal, it's a sign that you deserve your assigned rank.
Your teammates may be bad at certain things, but they are the same rank as you, which means they must exceed at other things which you may not notice. It's much easier to notice and point out the flaws of others.

I'd recommend watching back your own VOD and being super critical of all of your mistakes, ask yourself what could you have done better. Even if you think it's 100% your teammates fault, try and still find something that you yourself could do better. I can't really say much more about your gameplay without a VOD

Thanks for the response. I think your first point is answer for me. and yah, I'm not blaming teammates. their skill was having good reaction time and aim. while mine was game sense and stuff. I asked because i saw lot of tier 2 players got aim diffed past was now better than some tier 1 players wise aiming. so i wanted to know i can improve more or this is my deserved rank. because i got aim diffed in this rank. talking about holding, i cannot win 1v1 holding aim like others(unless i hold off-angle or crouch hold some times).

I can win so much clutch rounds, but cannot take fight and get first kills if I'm playing non duelist agents

Bro if u got 1 tap before u see them, it means how u peek and how u approach angle is beyond trash, which means ur game sense sucks lmfao

learn to abuse peeker's advantage as well as off angles my reaction time is doggy as well but u just gotta learn how to abuse angles
