SMN Novus and Piety?

[Dwill]

With the mp cost reduction to Bio II there is no way you can run out of mp, unless you don't/can't use Aetherflow every time it's up and if you have to raise 2+ times during same fight.

So my opniom is: No.

Actually, if you keep Shadow Flare consistently up and weave Ruin II between off gcd abilities, you'll run out of MP in the long run without a bard.
