mobs pushing characters around the map

I've had this happen quite a few times now, it's more noticeable on melee classes. Skills being interrupted is one thing, but why are mobs able to charge and physically displace me over a distance the length of my screen? I don't know how intended this is but it's a really weird interaction that i'm not sure why it exists. It's not dangerous exactly but definitely annoying in large numbers. I think unit collision in general seems pretty off as a whole. In POE 1 mobs were dangerous still but i don't think i should have to consider if engaging a pack is going to get me rag-dolled around the screen completely out of my control.
