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.
Despite the obvious counterplay, don't use your ult exclusively to counter Makoa ult. He can simply wait for you to die to use his ult, and you can charge yours significantly faster than Makoa can charge his anyway.
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.
