i used amarant zidane vivi and garnet but i couldve swapped amarant for steiner if i wanted. steiner+vivi=.freya is an amzing character but seems as you lose her for most of disk two when you find her again shell be a very low level. you pretty much need garnet or eiko for healing. so you hould have zidane,eiko/garnet,then id definetly have vivi,then steiner if you like using vivis sword magic but if not id choose freya or amarant(i think freyas better).
