Pally: Blast vs Divine charge?

My build in order of preference is probably now something like
1 Rush, 1 ACB, 1 Blast
1 Divine Shield, max ACB
max Divine Shield, max HH
max Blast, 1 MW
max Divine Charge
The rest (Achilles, Guardian, MW) can really come in any order.

Guardian is the only 4th job skill that's less effective with a shield. (it gives % resistance to mob magic/debuffs, but no blocking)
Since I'm mostly using 2h still, Divine Shield is very useful for damage reduction, probably cuts more than half my tiny pot use.
