"Recover 2% of life when you ignite a non-ignited enemy" is a new fire mastery talent
I'm not sure if 100% reduced ignite duration would work, but some combination of 99% reduced duration and faster ignite (say, Replica Emberwake to start) would likely get you . . . salutations?
Ideally of course you'd time it so one ignite would end just before your next attack, say with cyclone or something, so you could still scale ignite damage. But even without that, it might be some interesting survivability tech (unless there's a cooldown, which wouldn't be surprising)
