I'm still not sure if Wildfire is placebo. I know people hate on it.
And I know how it works, and the idea is that it's going to be a "base" for more relevant stacks of soulblaze.
Basically kill elite, spread 3 blaze with Perilous Combustion, those around him spread 3 blaze again and again with Wildfire, then Shriek for 1-6 blaze, that then spread 4 blaze with Wildfire.
It keeps the burn going. It just feels like I have more horde clear with it.
