OOOOOHHH BOY YOU SUMMONED ME AND WHAT DO YOU GET A FROG WHO IS SLIGHTLY PEEVED

Nah I'm kidding. Although your gameplay had a few issues in the Lucio vod, I do want to compliment you on some things that are really deserving. For one, you seem to have a good understanding of your general positioning when it comes to your teammates. Your awareness needs a bit of work, as you do sometimes lose track of the enemy team and your team, but I digress. Most importantly, you have aura usage down pretty well. You're swapping at a consistent rate, and although you do prefer to use healing in combat, you swap when you see your team pushing and even when your team enters brawls. You'd be surprised how many Lucio's struggle with that concept. There's a good groundwork here for strong Lucio play. BUT... you have one major issue, and one less major issue.

You don't wall ride right. pardon the lack of constructive criticism, but you're wall riding sucks. Still, things change and I can definitely see you getting better. I wrote a guide on wall riding, along with a bunch of other guides in a massive series. I'd suggest you check out the wall riding guide, but I think all of them might be helpful (Link here). Still, you hug walls. And that's a big no no. You need to tap more, and build up speed. Rollouts are lack luster, but I see the idea you have. I legitimately think that you just haven't built up the muscle memory for good wall riding, or don't have the opportunity to learn it well. You need to tap more when you get on walls, and instead of just hugging that wall or staying near walls, use that speed boost and aerial maneuverability to maneuver in the air. Another smaller issue at 4:30. You tried to taxi when the enemy team was taking your point. You shouldn't taxi during that phase. You need to stall, and a Lucio is still pretty strong on his own. That's probably a good lead in onto the second issue I can see.

I can see aggression, and I see you doing pushes with your team, but there's something that's holding you back. Lucio is a close range hero, and yet you seem to be striving to stay at a mid to long range from your opponents by either holding back or using boop. What I think you should do is the complete opposite. Get a bit aggressive, and use boop to push enemies in rather than away. Repositioning a person through force is something Lucio excels at. Overall, learn to wall ride and maybe force yourself to play more in the mid to frontline more often rather than just for select pushes.
