Burn level alone probably wouldn't save it. There's a possibility that, like suggested, it spreads like a wildfire to people within 1-2 range, doing the damage but not the infliction on them. So you get the damage on multiple people, but can still only burn one person. Either way, so long as that's single target it's probably not going to be worth it... unless it has a scaling boost that acknowledges that unlike black static or fleeing spectres, it's only ever hitting one person the way it is now.

A cooldown on silent spirit would probably keep it in check to some extent, so I can advocate to say "let's add a cooldown to that idea."
