Where's the new deathfire?

With the addition of the new masteries, weve seen a lot of various play styles emerge that were less available with old masteries. Tanks actually do something to towers, adc's can pass the atk speed cap, and you can run someone down and deal damage based off of how dedicated to Barry Allen you are. But, with the new runes implemented, something has gone missing. Where's deathfire? I came across This question when I was trying to theory craft a build for singed. There are zero keystones that provide damage from passive champions now (and I'm not going tanked singed, that's for nerds and communists). With all the options the only thing mildly suitable is the hunt keystone in the red tree, but that provides a burst of damage, nothing thereafter. I fear damage is going to be severely reduced in lane for champs who typically used deathfire, because the only damage options left are burst. Im sure there's something I'm overlooking here, but I can't see it right now, so rito pls help me dad.
