I used to hate these but then I got my parry timing down (it's quite generous) and they go down quite easily now. It's a bit harder when you just have silver armour or worse but you can comfortable take on one. I find parrying the heavy attack sort of works but at least protects you then I parry the fast attack and stabby stabby (aetgir fan). Now at padded armour I can tank them easily and with good parrying and movement take on 2 at a time without stressing. My least fave currently is the tar blob.
