No, that's for being lossless in DPS. As it stands currently, you get the current standard of 2 Sheltrons + 5 Clemency Casts (or more if you focus on regenerating MP) if you want to focus on survival. You only have 2 Sheltrons + no Clemency casts if you focus on DPS optimal gameplay.

That doesn't improve PLD's overall survivability because you trade more casts of Clemency with having lossless healing. You might as well put a separate oGCD healing skill for that if you want to increase PLD's overall survivability without DPS loss.
