On that Untraxion fight you should be able to get in about 41 Mind Blasts, but you only cast 37. You can get that a bit better. Your DoT uptimes look mostly good, though I think VT probably fell off during a fading light.
Getting Fading Light 7 times sucks though. I am not sure if you know but Heroic Will interrupts your casts for you. So you can keep casting until the last moment (I personally wait until 2 seconds on Fading Light and 1 second on Hour of Twilight). It takes some practice though, and don't panic about hitting the button
Also if you aren't doing it now I would say make sure that you recast your dots as soon as you get full stacks of the Will of Unbinding's buff (Combat Mind)/before heroism wears off.
The last thing is who was the lock who cast DI on you? 77% uptime is pretty low >< Not mention if he was the one who died, sometimes you have to remind them to recast DI.
