How to be a better Lucio? (Console)

So, Lucio’s my worst healer. Everyone other healer I can at least aim with, but my aim with him is pretty bad tbh. Not the worst, but can def improve. Also, I have trouble booping people off the map. I always feel like they don’t move nearly as far as they should, so I must be doing something wrong. Other than that, I can wallride pretty well and I’m a good healer/speed booster at the least. Any tips for improving with him?
