They’re only 5, and each one does about half the damage of my Rogues (all my skeletons are rogues, so the bonus from Individual Operator is split among 10 of them). On top of that, rogues can teleport.
My Deathknights are hitting for 40k with basic attacks, while my Rogues for 55k and up to 140k with Vile Flask and Shurikens (in AoE). The only small advantage Deathknights have is a minor AoE basic attack every 5 seconds. Death Blossom is pathetic, barely hitting 10k, and Necrotic Mortar not only takes time to cast but, last time I tested it, was also pathetic.
On top of that, my build is focused on necrotic damage (the type deathknights are supposed to do). Why? Why are they sooo weak?
