Ramako, Sun's Light - RF + Ancestral Bond charge generation

"When you or your Totems Kill a Burning Enemy, 20% chance for you and your Totems to each gain an Endurance Charge"

Looks like this does not work if the burn does not actually do damage. I'm running around with RF and my totems kill stuff. Mobs are burning from my RF but taking no damage from the burn because of Ancestral Bond.

So it's either a bug or the wording should be change imo.
