I was using a friend's, and I only played a little (Mostly to grind for him why he played my Disgaea for hours on end...).
Uhh... I pretty much screwed around the lower floors (He had just gotten it, so he was only up to the 3rd floor), with a:
Front Line: LandsKnecht, Ronin, Dark Hunter (For the LULZ. Named SexyTyme, my own creation)
Back Line: Alchemist, War Magus
His characters were named LandNite, Alchmist, WarMage, Ronin, etc.
It was lolcakes.
I reprimanded him for not being close enough to his characters to remember anything but generic names.
