Don't use the Solar Blessing talent when fighting Willo! She can simply place her Dead Zone on top of where your Pyre Strike stops and completely negate the healing.

Zhin has a drastic advantage in both mobility and survivability over you. Try to stay near teammates so you can't be singled out by him.

When at a distance, keep out of Kinessa's line of sight. Her sniper shots can quickly bring you down, and you're likely to be her primary target.

Most of your abilities (including your ultimate) have long and noticeable startup times. Torvald's Nullify will interrupt those, so wait until he uses it or buy Resilience to reduce the downtime he can cause.
