De-aggro Improvements?

I don't know if this has been addressed before, but deaggro needs to be fixed for Hardcore mode, I've died on both of my hardcore profiles from finishing a quest and while waiting for the dialogue to finish, getting attacked from behind by a bunch of mobs at once. Also when getting resources the deaggro can be very finicky resulting in the mobs attacking once and pushing the player away, stopping them from harvesting, then attacking again.
When the player is busy doing something could the mobs be instead pushed away instead of just idling or something or have some type of cool down before attacking again? Or maybe just clearer causes of deaggro would be helpful because dialogue does not seem to be a cause when it definitely seems like something that should be.
