I'm running the same party again, Knight, Samurai, Princess and Mage. They're generally the classes I like using the most, Mage and Samurai do lots of damage, Knight protects them since my party is very squishy (2 casters and a glass cannon), Princess has decent physical attacks but more importantly Moonlight's Poem and Angelica Cage are very useful and make my Mage rain even more destruction.

My party could work with a Healer (Craft Mana is oh so useful as well), but Moonlight's Poem is too good to pass up. Plus I'm using a hybrid Samurai now. With all the stance switching my Samurai is going to run out of mana quickly unless I have Moonlight's Poem up.
