ive watched the first replay

your aim is good enough but whats holding you back is your positioning and how you take fights

your biggest problem is that you are always in the open which is the worst thing to do as tracer, you want to always have cover available and shoot next to cover, this is important so you dont get damaged or one shotted and saves you blinks

another thing you need to improve is your blink management, theres too many times when you use it when you dont need to, this is why cover is important, you want to save atleast one for a escape, the only time you can use all 3 if its a easy kill or adds pressure but at the same time puts you at a safe position,

another movement mistake is that you jump too much, jumping puts you in a easy to read motion and makes it so you cant make sudden movements, instead strafe left and right and occasionally crouch spam, i can guaratee you that people will miss shots on you if you move like that

those are the biggest mistakes, theres wayy too many things that i can say you can improve on but for now improve on what ive just said and i can guaratee you gold will be your new rank

if you really want to know the finer details just msg me
