I think using scatter is amazing but I think depending on Loaded for Bear is the wrong move. Makes damage too important. I have 20700 damage without crit, ias or crit damage (just dex) and I watched Sarkoth not die pretty often. Replacing Loaded for Bear with Ball of Lightning adds so much more variability since it's not limited by the remaining hatred and the bot can use Steady Aim instead of Vengeance.
For people who are having problems killing him with Scatter+Loaded for Bear you can just replace Loaded for Bear on your character with Ball of Lightning and then increase the sleep value for MouseDown("right") in line 825. I would start with something like 4000ms and then work your way down if you notice you're killing him faster than that.
