I noticed this routine sees every target as an enemy. This means it would never heal a friendly target and makes it rather useless in arena's. Can you add support for the arena by making it able to heal/dispel party members? Right now I must turn it off to make any heals (toggle options are just too slow). If you add selective targeting support all together, you could also recognize targeting yourself and see if healing is needed. This would mean you could replace the current mechanism (spamheal by hotkey). This would also be very handy for battlegrounds.
