You don't need KJC as Demo as Touch of Chaos can be used while moving and Fel Flame is barely any DPS loss if you're pooling Fury. You can also keep movement to a minimum with Leap and portal.
The first thing I noticed is that your DoT uptimes looking at Feng (the most Patchwerkish fight) and Spirit King (the heaviest movement fight) look really low: 75% for Doom and barely 50% for Corruption, that is a major DPS loss through both damage and Fury. Really, I know simcraft says 'always refresh through ToC', but it's only about a 500DPS loss to manually refresh all the time - that kind of difference is easily converted to a DPS gain when Fury is pooled intelligently rather than used up (240 at a time) just to maintain DoT uptime.
The other thing I'd look at is your Life Tapping. It's very easy to go OOM and stand around confused if you don't manage it correctly; be very aware of Soul Fire's high mana cost and never chain more than 3 together without breaking to Life Tap unless you're very close to the end of the encounter and have enough mana to see your spamming through. Also during the execute, it's very easy to let Corruption drop if you're not careful (see my Feng parse >.< ).
These are my last parses
