All the class specific weaknesses from this expansion have obvious links to strengths or specific archetypes of that class. Underprepared seems like the worst of them by far, because this is the most focused of the cycle and Survivor have diversified their archetypes.
Almost all Guardians can fight, all Seekers can draw cards, all Rogues can gain resources/actions, all Mystics use their arcane slots. But not every Survivor plays anything resembling the super low to the ground style required for this card.
Overall I really dislike the design of this card due to the variance in effect. If you are Patrice with double Cornered this card is a joke but for any midrange investigator this card is worse than Amnesia and Paranoia on a single card.
