That's why you have those instances where she'll heal a DPS at 75% over a Tank at 20%, they are just a smidgen closer. I think that in an update she was given a new threshold limit to counter this, but it still has its issues; like if the new threshold is 50% but the Tank is at 51% she'll still target the DPS at 75% if they are closer.
The system isn't perfect. I wont say that it is, but what you are asking for already exists, it just needs fine tuning.
