I think all the classification does is make a clearer classification for BPD so that those who have some traits but not BPD are not misdiagnosed. I don't honestly know the ICD 10 to compare, but I think there has been a problem with over diagnosis of BPD, and this criteria helps eliminate that a bit. I think some Ts are lazy and don't look deep enough, and it was easier to give this diagnosis. now maybe it will be a little harder.
