Yes, it is a bug. Scorpions usually hit for 2-3k and then can 2-hit you. Bankha Pafh, I presume, is NPC that OP refers to, is also putting bleeds that 2-hit you.
I presume they'll be adjusted in upcoming patch, but like diggers in Sarlo, it might take a few months. But then they are quite a bit worse than diggers, so maybe fixed sooner.

Oh, and people who have more than 3 classes are clinically insane.
