Game Mechanics: Low hp aggro kiting

[Nirgon]

I do recall in classic that a mob would immediately jump to a player who is under around 20% hp.

However if that low hp player continues to kite it, and never goes above 20%, should it continue to just blindly chase that player regardless of any additional threat generated/damage done?

I never used that tactic on live (but use it here) so I can't comment, but this can be used to trivialize content right now.
