Oh yeah, what character setup you guys using?
I myself have been going like this:
Vaan - sword and shield/katana, heavy armor, some use of green and white magick, some use of technicks
Ashe - sword and shield/ninja sword, heavy armor, main overall magick user, no use of technicks at all
Basch - axe&hammer and shield, heavy armor, little use of green and white magick, lots of technicks
Balthier - gun, light armor, some use of green and white magick, some use of technicks
Fran - spear, heavy armor, lots of overall magick, a few technicks
Penelo - bow, light armor, main white magick caster, lots of overall magick, very few technicks
I mostly use two fixed teams in order to lvl up evenly, alternating the use of golden amulets (I know I could buy 3 more but I'm just too lazy to do it :~), vaan/ashe/balthier and fran/basch/penelo, sometimes mixing them according to necessity.
