Hi Frontright,
Looking at your Armory it says you are taking Archi's Vengeance over Kil'j Cunning. I can't tell if that was the setup you were running during that Garalon fight, but I would highly recommend taking KjC. It should help you a lot during kiting as well.
Now looking at those logs I see two points during the fight where your damage drops to Zero The first time lasts for almost 20 seconds. The second time is much shorter, but happened nonetheless. Keep those DoT's rolling man! 81, 86 and 79% up-time for Agony, Corr and UA respectively for the fight overall is definitely bad.
I'm
