One warrior, 2 mage (one fire/earth another wind/water) and an archer/rogue whatever you want
Pretty much, although I'd say Ranger over Rogue for a first playthrough if someone is asking for advice, claiming that they aren't that good. Ranger has some explosive combos with the elemental arrows early on, and later can blow shit up in a major way with just skills. You could always just play a "Rogue" that also switches to bows to use the elemental arrows, but then you'd end up having to spend AP just to switch your weapons again later.
As far as Fire/Earth is concerned, you may as well add Witchcraft as well due to the extremely long cooldowns and the long periods of time you go without seeing any new spells. Plus, Oath, Malediction and Charm are pretty great. It might take you a few more levels to get five in two schools, but that doesn't matter much. You can just focus on one first after those three are all 3-4. Most of the level 15 spells have such an absurd AP requirement too that you'd either just initiate the fight doing it and then not worrying about them again, or waiting 2-3 turns to do anything.
