Assuming you don't got Vengeance , perhaps Vengeance didn't proc.
Another thing which is clearly wrong is "Seal of Command Crit" .
The damage output by Seal of Command when it Crit should Multiply instead of the damage in the current picture .
In your case Command crit should been something like 1.2-1.5 k dmg more/less.
Which i already know all those bugs but i don't care anymore reporting them since they don't care of the most important 3 reports i did .
(refusing blizzard evidences for assumptions made me don't give a damn for bugtracker) .
So i let you guys do whatever . Ill keep evidences for myself.
