Always happens to me when dealing with a big group of enemies, if it's obvious you're stuck but are able to move it's clear that you're actually still standing in the group of enemies even though it may not rubber band you back for quite a few seconds. You can usually tell if you are still taking damage. I am constantly tabbing out for music and what not so the above post actually helps me understand why the hell this happens so often... I also have perfect ping most the time. I can't see how hardware would effect rubber banding as it's lag afaik.
I can only suggest that you watch where you walk, it always happens when you are blocked by something like an NPC or an object. Try going around things instead of letting your character collide with it.
