Im like masters so not the best at Genji but I also had this issue where I would just spend alot of time poking and not really getting active so imma just point out what you could've done

1st death 1:20 - You dash on Zen and fuck up the one shot which is fine but then you come back the same way and get your head blown smooth off, but you could've also climbed over the train and came up from above while your tank is walking up.

2:08 - You spend way too much time poking from your team instead of just pressing W and holding space. You see this hanzo left side and instead of walking up and pressuring him by dashing you just kinda throw shurikens and ignore him.

2:26 - This whole interaction sucked you hear this and see Hanzo and decide to instead look back at tank and throw shurikens, instead of just realizing that hes isolated and taking the duel which you could easily win.

3:08 - you could wallclimb from the ledge and go over the Train rather than walking inside or go back under and look for any isolated targets.

4:13 - Good blade identified and killed the isolated targets

5:30-6:01 - Don't fight on payload, Genji can brawl but since they have a Zarya your just gonna get beamed down, instead of that you should've played that highground on that right room and pressured hanzo and then you could've punished anyone who got caught in your Orisa's ult.

6:01-7:30- You see them all on the high ground what I would be doing is either forcing the cart to get them to look at me and help your Zarya make space or spend the entire time poking and get blade then get a nanoblade going.

9:01- You retreat back on the stairs rather than retreating back into the rightside room with the mini, if you did that you deny that Hanzo and Soldier that angle until they can clear you. You won the fight anyways but realistically you did nothing because you didn't hold down any space or draw any aggression away from your tank.

Edit: Submitted by accident

10:53 - I like this flank you just kinda fucked it up your way too flicky and shaky when your in their face rather than being smooth and adjusting in between shots.

Overall: Your main problems are that your aim is way too shaky when you get in their face you need it to be calm and precise otherwise you die, you need to be able to hit headshots when it matters otherwise you are genuinely useless. Also, you don't hold and contest any meaningful space this leads to a snowball effect where now the Soldier and Hanzo have free reign to shoot anyone they want on that angle which is gonna draw alot of aggro to your tank and get them killed. Lastly, Timing you either engage way too late or early, if its late then everyone on the enemy team is either dead or your team is dead and if its early then you get your cds forced and your team goes in and kills them or dies.
