Chinese server players should rarely contact DJ, and their gameplay is more favorable to novices or ancient DJs. I can share some of my views here, or watch videos of foreign server bloggers (Lucio in foreign servers is indeed better on average)
First, look at the scoreboard. What is the ratio of your DJ's healing aura and acceleration aura? If it is not 6 to 4 or even lower, then your dj may not have changed your mind yet.
requires speeding offensive retreat, while treatment requires recovery after combat and war. This is very similar to the angel's yellow and blue line, but dj is the aura gain, so unlike angel only tilts resources to one person, dj needs to consider many units, which units need which resources more, and dj needs a global perspective more.
requires a long time of practice, and everyone has a different understanding of when and what resources to provide for DJ. In short, the acceleration halo ratio of dj is above 0.4 (if it is a pure yellow circle, the angel is more suitable for you).
passive skills require players to practice, which is a watershed that distinguishes old dj and new dj. How long do you try to hang it on the wall? Use your mobility to provide resources to your team. Usually it is to be stuck to the wall on the ground. Jumping over the wall can provide yourself with explosive movement speed and can be superimposed.
