Changes to Personality Flaws
Most importantly, Major Personality Flaws are not allowed. From what I’ve witnessed, it’s easy for some players to forget or ignore roleplaying these complicating personalities and problematic to try to enforce such play, so these flaws become nothing but Merit points in these cases.
Minor Personality Flaws remain playable as described in ArM5 with one addition. If you take a Personality Flaw, you must have a related Personality Trait at +3 with some exceptions (Ambitious, Driven, Hatred, Obsessed, Oversensitive, Nocturnal, Noncombatant, Poor Memory, Prohibition, Transvestite, Vow).
