Ideal Damage Dealing Party for bossing like horntails, zakums

Pre BB, It was almost like

1 dk 1 bs 1 se 3 nl

Post BB, I wonder if it is

1 dk 1 bs 1 battle mage 3 mechanics

or

1 paladin 1 bs 1 battle mage 3 mechanics

My question is actually, which buffs more? Advance dark aura or combat order or sharp eyes ?

What about a post bb pink bean party?

bam + pala + dk + 3 mechanics or
bam + pala + dk + wildhunter + 2 mechanics ?

What is really the ideal damage dealing party with bs n dk inside, and with a dk inside.

Just curious.

or even bam + 5 mechanics ???
