You have to pay attention to your heal targets. You have the ability to heal multiple targets for insane amounts in a short period of time, but you also need to look out for your heal meter to the right of your crosshair.

Be mindful about using your Fade ability. Spamming it can be tempting due to the 6 seconds cooldown, but you want to focus on using it as an escape tool most of the time. Occasionally you can use to engage or to gap close when you want to reach a low hp ally, but be very mindful about that.

Coalescence can feel a bit underwhelming at certain times. Try to use it in situations when you are out of your heal juice, or if you lost an offense hero in the beginning of a fight and you want to make up for the lost dps. Also, don’t forget you can’t use Fade while Coalescence is active!
