This is an Infested specific build for SP, but can be altered for any situation.
With the [Blood Rush] and [Condition Overload] nerfs in effect, many have been met with lowered red crits and less damage. Most would simply revert to using Primed Pressure, and that's fine. In this build doing so nets you around 280% CC, which still hits red plenty. But who doesn't want red all the time?
Going this route does lose ~28% additional damage (PPP 165% vs SacP 137.5%) but the push into the 300% CC threshold is worth it for me.
Still lacking damage? Consider looking for a CC/MD or CD/Range riven.
This opens Primed Reachs slot, where you can then add a mod such as [Gladiator Might] for additional CD and the 110% CC buff at 12x combo multiplier.
