i would go for:

inquisitor paladin
ranger -> cleric (dualed as soon as possible)
kensai (dualwielding katanas)
som kind of thief
sorceror
cleric/mage

this way you will have acces to all druid, cleric and mage spells, you will have a very powerfull despell from the paladin who serve as your main tank, the ranger cleric can also do a decent job of soaking up the damage. The kensai is there mainly to dish out the pain, the rest should use ranged weapons IMHO, slings, shortbows and such...
