After quick glance, SW
usage is not optimal and is nearly lower than what it should be on every fight. I have shorter kill times and nearly double the usage on fights such as Tyrant and Assault (I have a hard time sniping as well, due to heavy raid aoe dmg that we run with, but yours is still significantly lower than what it should be, make this a focus to improve upon).
Reflective shield has minimal usage in your logs, which can be used as a filler during movement (if no other instant cast is available and dmg is incoming).
Searing Insanity on Kormork is low, maybe this is due to hands being spread? Cascade is much better here than DS.
If you find adds die too fast on Kilrogg or you dont get sent to his eye, try CoP.
On the fights I looked at about ORB management (Tyrant and Kilrogg) you had little wasted, so you got that going for you.
