Wizard - bard will help, though also access to stronger gear sets or weapons would help.
Monk - Access to mid slotted headgear
Blacksmith - Much stronger weapons or some custom gear to make this class actually dangerous to knights either via damage, status effects, or woe tankability (like a ck effect smith only axe)
Assasins - Adding the Drill katar and making it usable by assasins might help, though there would be balancing issues with rogue. Like Smith, Sins need an upgrade though it does not have to be pure damage.
Just some thoughts, maybe this will be sorted out once all classes becone available. If not, please consider some modifications to the less sought after woe classes to make them more viable.
