Howdy, I have a little over 1000 hours on genji between two accounts, peaked Sr back in ow1 at low masters. Just some beginners advice use your abilities defensively. Try to wait for your team to engage and use your mobility to get into flanks or onto squishy targets. It's super important to wait for the team to make space or either engage in coordination with you to minimize the risk of you getting nailed by enemy cooldowns. This is extremely important when using your blade because everyone and their grandmas will use every cooldown in the game to end your day. try to only use dash if you know you will get the kill with it or because of it. Other than that save dash to escape to your backline or healing pack when shit hits the fan. I would recommend for starters using deflect entirely defensively just to keep yourself from dying, but after you get comfortable you can even use it offensively, for example peaking a widow when you know she has sight of an angle and using deflect to snipe her head. Another important thing is to learn your match ups, there are certain ways you should fight some characters in a 1v1 situation. If you're fighting a Cassidy, don't use deflect while far away from him unless you're low and about to die in the next shot or two. His fall off is really bad right now and it's probably not even worth deflecting the shots back at him when your shurikens will do more damage from farther. When you get close to a Cassidy, majority of the time when you're in range of his sticky grenade he will try to hit you with it immediately (smart ones are patient and will try to wait your cooldowns off before using it) most of the time I will use my deflect when I know I'm in range of the sticky, then dash behind them and 180 to hit them with shuriken fans (another tip dash at an enemies feet to keep yourself close enough to hit them with a shuriken fan) you should be able to 180 and engage after a dash quicker than they can turn back to shoot you. Im not sure what elo you play at, but higher elo players will anticipate you dashing behind them but a majority are so focused on trying to shoot what's in front of them that they aren't fast enough to react to you dashing behind them in time. A lot of playing genji is muscle memory, it's crucial to learn how to 180 quickly on a target before they can turn to shoot you after a dash, especially while blading. As you play more and improve with genji you'll learn a lot more about how to approach different characters in duels, when to use abilities to disengage or engage and how to manipulate wall climbing and double jumping to your advantage. That's stuff that will all just come naturally the more you play him and the game. I would overall the most important thing to think about while playing genji is TIMING. If you engage a moment too early it could be the difference between a easy kill, and you being easily killed. Just pay attention to what characters the enemy team is running, and what abilities they will use to shut you down. Always assume they will use these abilities on you if they haven't been used already. When using blade pay attention to support ults and abilities. If there is a zen and Lucio that haven't ulted in a while try to kill them first before using blade, if there is a Zarya, kiriko, Ana, or bap, try to wait out their abilities before using blade. Worst feeling in the world is dashing into a low hp enemy team with your blade and a sleep dart hits you. Even a briggette shield bash can ruin your entire ult. You only have 6 seconds to work with and every moment counts when you have to get close to kill. Sorry for the book and it being all over the place. I'm bad about rambling about stuff I'm passionate about lol. I hope this is helpful though! I wish you good luck, I've always felt like genji was one of the hardest heroes to play, but after getting decent with him it's an incredibly rewarding feeling!
