Im currently playing a pure ranged party, consisting of 2 minotaur missile rogues, 1 minotaur throwing rogue, and 1 insect air-mage.
They do an insane amount of damage in short time, but have to be extremely careful not to get to close.
Of course the 3 rogues have all maxed strength, and rest of the points in vitality. All skill points go into missile/throwing.
