Personally I would divide teams based on balance of abilities. I basically think each team should have at least one strength based melee combatant, one dex, and perhaps at least one to two spellcasters based on the need...Though character interactions are something else to consider.<br/><br/>For example, Yule and Yuka seem to get along well from what we've seen so far. However, Y'mir being the flirty one and willing to flirt with just about anyone who catches their eye would make a party that hast let's say Naru and Yule less ideal. Behm and Naru (once Naru calms the fuck down for a few seconds) might actually get along pretty well, but putting the two together could throw a teams balance off depending on who else is in it.
