Since 2.0 makes most of pre-2.0 party plans invalid or at least incomplete/misleading, lets start over with a new one here.
So my suggestion as a start:
Lise
Vanadise with INT capstone (equip any weapon), take weapon from Evil Shaman (nerf all enemies)
skip Power Up and Thunder Saber = 3 buffs & heal light; need to get Mind Up asap or the slot might be blocked since the previous spell is only an upgrade
auto-buff armor
Charlie
Evil Shaman with LUK capstone (team uses less MP), also take the class weapon
skip protect up and transshape
most importantly learn demon breath asap then anti-magic
Kevin
Dervish with VIT capstone (draw aggro)
skip Anti-Magic (shaman has that) and Half Vanish, so has the 3 missing debuffs, energy ball, analyse and moon saber
go for auto-debuff set bonus
enjoy your crippled enemy team - all buffs on auto, all debuffs except mind down on auto, 2x all stat downs beyond that. for proper mind down you have shaman with demon breath.
