Info to help update your KC script, here are at least two of the items that have KC on them, I think there are a couple more out there.

Fungus-Covered Mug (Bar-Brawl)
Mirrored Chamber (mission crate)

I can't say I've tested them this xpac but I know in AoM killing chamber was awful dps. IMO dmg procs in general are going to net less vs cb/pot/bolster proc items.

yes, they still parse pretty bad. Posted this from someone asking on another post.
