here I go again...
give basch an axe with a siled,also give him your heaviest armor you have
give vaan a sword and a shield,either give him heavy armor or light armor your choice
if ashe is your white mage of the party then give her a bow and arrows,if she's not then try something like a katana
also remember to buy he bazaar items especially iof there bows because most of the time they give better arows
