Best path to “hundreds” of PotD aetherpool?

[Omedon]

The best are widely agreed to be:
MCH
RDM
NIN
PLD/GNB

And, believe it or not, MNK gets an honorable mention.

I assume this is based on a “round them up, burn them down” tactic? I honestly haven’t soloed a deep dungeon before so I’m likely going to read some guides before I sit down to try it.
