Hi,
I was just looking over the game and can give you some general tips and pointers for your macro/ team fights. It seems like a lot of times as tracer you are engaging in fights a little too early/ too late. One point I notice is 8:54, your sojourn just died over extending and winston is primaled in your backline. You know that solder kiri som are together and you try blinking in and snagging a pick but get your recall forced. Around 10 minutes is another example, while you did a good job of disengaging, you marking an ana while you are low on resources and your team is on respawn timers. This inevitably gets the team to peel for you, forcing out your blinks/recall and eventually losing a 1v1 to soldier because you have no resources.
Another thing I noticed was when the sombra/winston would dive your backline, at points you would leave your tank + sojourn to go peel for a winston sombra. Sometimes it can be a good idea to peel for your backline but you want to make sure you are looking at where your tank is on the map and seeing if they are pushing up or not. An example of this is at 1:35, The winston + Sombra are diving your backline and tank is on cart pushing. You see that your tank is engaing on an ana with cart and decide to leave youjr tank and attempt to peel against a sombra winston.
Your micro is pretty good on tracer I like what im seeing with the blink melees and predictive aiming. As you improve with your engage timing youll notice that your blink uptime will be higher allowing you to engage more frequently ( less mistimed engages = less damage received before dive = less resources wasted)
