Benefic 1 and Cure 1 do the same healing, but AST is cheaper. There used to be reason for it being cheaper but 3.07 buffed the potencies without touching the MP cost
I'd argue that this is in fact the reason why Gravity is cheaper. In the realm of ASTs (few) DPS spells, their potencies are in line with their MP costs relative to the other two healers. Malefic II is the same cost of Stone III/Broil. Combust II is stronger than Bio II and it has a higher cost than Bio II. Stella is the same cost of Miamsa but Stella is outside the normal damage rotation. The only odd one is Gravity.

Gravity has been the same since AST's launch but its mp cost is lower than Holy, It has the same potency of Holy but it is missing an effect therefore, a lower mp cost is justified. If they were to give Gravity like a Slow or Stun, I'm sure they'd raise the MP cost as well.
