note my last peasant party in MM8 (KNVCK).As a matter of fact, I almost never casr offensive magic spells, except an occasional Souldrinker or three in the Planes now and then. In MM9, I usually only travel wiyh a Priest, and only use offensive magic (Poison Cloud) when fighting the Mega-dragon. The other three are 2 Assassins and a Gladiator.
I like the default team in MM7 the best but it is balanced, neither might nor magic heavy.
And my favorite team in MM6 is 2 Knights and 2 Druids.
