Maintaining a high cleric stance uptime/lessening the time frame I'm "locked" in cleric.
Also, Medica II has a slightly higher potency per mana compared to Aspected Helios.
Freecure procs at 15% effectively bring cure I's potency per mana to 1.06 from 0.9 (assuming you take advantage of every proc). Bene is at 1.13 for comparisons sake.
Regen/A. Bene was already beaten to death.
Helios and Bene II are infact more mana efficient than their counterparts but in circumstances that you're able to use Cure III on the entire group, it is more mana efficient than Medica and Helios.
And then there's the party MND buff.
Edit: I'll play around with the suggestions regarding A. Bene and see if it'll mesh with my playstyle in A3S.
