Please let bosses drop loot. I killed Sepiks several times and he never dropped loot. Just the Summary at the end. I think he should drop those shiny engrams.
I do believe they should drop loot it is frustrating sometimes to fight the devil walker multiple times and NOT get anything. I also think when you pull up the ghost he should mark all nearby loot for you so you can do a quick check for the loot, instead of just straight out missing it cause it fell in some weird place so you couldn't find it or worse not notice it come out at all.
