Photoshop :: Spot Healing Brush With Stoking Path?

why the healing brush is so useless on stroking a path.  It always (apparently no matter what setting you use) creates a soft blurred splodge as opposed to  - well - what its supposed to do.
 
I've just spent 2 days creating what is (IMHO) a totally awsome action that highlights moles and skin blemeshis (and does so by finding details, not by colour or brightness so should work on most skin tones), creates a path based on them, and then totally fails to patch them because the implementation of healing brush stroking on paths is so rubbish.  THe path created is quite complex of couse, and extends over most of the image, its not like stroking a single path where spot healing appears to work.
 
THe nearest thing I've got is to create a pattern based on a clean patch of skin and the to use the healing brush set to a pattern. This works OK for this person, but will be rubbish on someone else.  I've also tried using the patch tool, which is also no good. Content aware fill also produces the soft blurry splodge.
 
the 2 screen grab on the right are created by manually using spot healing brush the combination of path creation and stoking with the healing brush could offer up SO much functionality I think adobe should investigate.  I've got at least 3 actions now that are waiting to go out the door that will save retouchers hours and hours of boring spotting work.  It uses frequency separation, too.
