I know that this is a bit late, but I thought I'd share my thoughts and strats on the thew bomblet NM.
We did it with:
pld, brd, sam, drk, war, sch and it was easy.
All DD /thf and trick attack the tank, sch keeps phalanxga up as much as possible whilst keeping the pld alive and keeping the nastiest effects off of him (paralyse and silence firstly) the brd keeps ballads up on the tank and healer and then marches the DD.
This is how we were standing.
<sch>>>>><BRD><<<<PLD><NM><DD^v>
Means the brd can hit the pld and sch whilst staying out of range of the nastier moves, then run behind and it and hit the DD with marches whilst avoiding moves.
BRD can also remove the DD status effects if they have time.
went 2/2 with that strat, and it was pretty smooth.
