When u hear the Kinetic Burst sound or see the animation, use your shield to tank the next hit.
For her dash use Commander's Grab, that has a bigger hitbox, in the direction she is looking.
And when she ults, use your ultimate to take her out.
Willo's hitbox is very large and she's slow so you have the advantage if you're able to aim for her wings. If she decides to fly away from her original location, don't track her, predict where the arch will slow down at its peak and shoot there.
Makoas LOVE to flank healers, and he can deal a lot of damage to you. Your best bet is to use Agony, and stun him whenever he comes after you. This will give you a good chance to run away or ask for help from your teammates.
