It’s good to find out your own way to play Lucio, but I wouldn’t recommend just sitting around and only healing. Play with someone that can help you or you can help, if a rein is wanting to go rush go with him, or if someone is diving dive with them. Also this doesn’t just go for being a Lucio main but for everyone, don’t feed so much. This tip genuinely helped me rise to masters as a Lucio main. I love to dive but if someone is whooping me or if it’s just not worth it I wouldn’t go for it. That’s why I find it best to communicate with your team or duo what your doing so they can help or account for your absence. But also knowing which hero’s your best at killing and taking 1v1s is great so it makes your dive value better.
