the build is missing damage multipliers.
Pistoleer and Counter Talents give 0 damage for this build.
your Crit DMG is only +50%, so DMG from Deadly Strike (from DeadEye Talent) is 1.5 x 2 = 3x Deadly Strike DMG.
when Crit DMG is maxed, Deadly Strike looks like this: 5 x 2 = 10x Deadly Strike DMG. if you want to put Brutal Mythic on your Chest, Deadly Strike will be 15x DMG.
Relentless is the biggest damage boost on this build.
another thing is that, as a Farm Build, you have 5 affixes for Farming instead of DMG. also, KnightCharge is a Warrior Skill, so it’s hard for a Rogue or Wizard to get good DMG with it if not using +5 All Skills on both weapons and maybe +10 KnightCharge on the Pet. Identity Set increases DMG of Skills from other Classes.
look at the affixes in the Codex > Dictionary to see what other affixes there are that boost damage. some can be rolled with crystals and some can only be found on Items.
hope this helps.
