Culmination Support Infinite Damage Bug

Culmination support appears to be bugged in the way of infinite damage scaling for certain multi-effect skills. Its usage with Rake has already been reported on these forums. For myself, I tested Culmination with Primal Strikes as well as Whirling Slash. Not only does the counter not reset upon using either skill, but the skill it's socketed into, itself, raises the counter. Despite tooltip DPS not being affected, I confirmed the damage increase was real.
