This was just to get the ball rolling with ideas, we would be effectively be focusing on life/mp instead of just mp. I only mentioned three, which would affect the summoner as well in terms of mp management, for the person above. This would change the concept of the scholar and then other spells could be based around it. I honestly can't see how any scholar runs out of mp. Between the 20% on aeitherflow, the energy drain, the minute cool down to aetherflow, the heals from fair costing nothing....etc. So yes changing the job to a healer based more upon its own life would make them more unique and as the game matures more spells could be added to support it.
