Royal Jelly is a breeze. I came out of it with Erase and Ni.. I also got an Archer's Ring to drop, but I shall never speak of
that episode except to say that it never made it back to the AH...
You may wish to save your Beastman's Seals for later unless you need Ni/Erase (most people need at least one of these). A popular one that has fallen by the wayside due to dropping prices is Wings of Fury which can be duoed by two BSTs. According to your roster, none of you are BSTs, but that's ok because there's more than one way to skin a cat. Check out
Alla (even though I hate to send you there)--strategies are plentiful (but not always useful).
If you want to know (in general) what the most valuable BCNMs and KSNMs are you can look at this page:
http://www.ffxiah.com/bcnm.php. Just remember to select your server in the upper left to make it as accurate as possible, and note that it
does not take into account relative drop rates for the items in the drop list--the value is taken as if each item has the same drop probability and furthermore that there is no significant variance in the number of drops per run between the various BCNMs.
I would go with the Royal Jelly idea. Two DD's and a WHM or RDM--very simple. Ranger's get the love here because of the
Binding Jelly. Monks get the thumbs down because of utter lack of ranged attack when bound. A bad bind could conceivably cause you to lose, but it's a rare thing. It's seriously easy... Gravity is more effective than Bind. WHM cannot use Gravity, but they
can use
Haste--Column A/Column B stuff use what suits. Elemental Seal is excellent so either WHM or RDM subs BLM for that. I think I give the gold star to the RDM though, because of
Gravity,
Convert, and their better physical damage rate vs. Slimes using an En- spell (The mage is advised to assist in the killing of the last 1 or two slimes).
