so the tier set 4 pc makes ravager a 1minute cd. are we taking this over the random proc ravager for m+
No.
AFAIK the bleed doesn’t stack with each additional application (Ignite/DW effect) it’s more akin to something like Rend where it’s flat damage and reapplications will refresh the duration + grant the bonus pandemic duration ontop of.
Given it’s upkept by both free revenge procs and ravager procs there’s no way you’re using 1min ravager over the proc variant.
