See, there's been a lot of complaints about the new Clinic system. Aaand there's been a lot of complaints about the old Clinic system. SO. Here it is, my proposition.
 
As it stands, the HP scale goes from -10 to 10.
If a pony is 3-10 on HP, they are free to leave the Clinic.
If a pony is below the aforementioned range, they are strongly advised by the doctors in the Clinic to stay and heal up until said threshold is reached.  
 
-REGAINING HP-
If a pony is in negative HP, they McFucked up and must pay. So... They may only gain 1 HP per 12 hours. Doctors may roll with no modifiers, if they roll a 10 or above they receive 1 HP.
 
If a pony is in positive integers HP, they may be healed by the old, fun-first Clinic rules- If the doctor completes a task, be it disinfecting the wound, bandaging it or whatnot, then they must roll.
If roll is above 18, then the doctor must roll a d6.
If roll is above 10, then the doctor must roll a d3.
The second roll indicates how much HP is gained.
*NO MODIFIERS TO ROLLS, SEEING AS HOW ONLY DOCTORS ARE ABLE TO PERFORM THE ACTIONS*
Tasks are all things considered positive for one's health- E.G. Disinfecting a wound, bandaging, setting a cast, whatever.
NOTE:  Two doctors cannot both successfully bandage the same wound and roll for double the HP gained.
 
-REALISM VS. KEKPLAY-
 
See, disinfecting a wound is pretty goddamn simple.  So, here's my suggestion.
*WHEN AN ACTION IS PERFORMED BY A DOCTOR, UNLESS THE ROLL IS A CRIT FAIL THE ACTION WILL SUCCEED.*
What does this mean?
It means that if GreenLight rolled a 7 to disinfect a wound, he disinfected the wound successfully, but the patient will not regin HP.  Liven will NOT be able to try to disinfect the same wound for HP gainz.
*ROLLS ONLY DETERMINE STATUS OF HP, NOT WHETHER OR NOT THE ACTION IS SUCCESSFUL.  IT'S PRETTY GODDAMN HARD TO MISS WHEN DABBING A RAG SOAKED IN ALCOHOL ON A WOUND*
 
-CRIT FAILS-
You dun goof'd.  Whether you >kissed the wrong lips for CPR or put a touniquet on a fleshy pringles can, the idea is that a crit fail on an action leads to a comically absurd and horrendous thing, hurting the patient for 1 HP.
 
-DEATH-
See Lucyne's rules for rolling to evade death.
