I don't know what it look like pre-change (probably a red shadow flare, eh?)
The scrolling fire effect that is only visible near the edges used to fill the whole circle and it was brighter. Like shadow flare is now minus the bubble and orange instead of purple. Now you can barely see the effect at all. For whatever reason they changed this but didn't change it with shadow flare. IDK. But having the cones draw on top would be a simple solution without modifying the effects of the skills.
