Anyone else finding the new bosses common drops kinda lackluster for how difficult they are?

I've mostly been killing Vardorvis because I think it's fun and challenging, but in the last 5 kills I've made a total of 25k (mith javelins, lots of lava runes, etc.) and definitely burned more than that in supplies. Maybe it's a skill issue, but I am definitely in the hole quite a bit when death costs are so high and it's super easy to die at Vard.
