Why is lineage important?

[Ironbear24]

My lineage is Edmund Parker who taught Stephen Labounty who then taught Jose Delgado.

I've been punched, kicked and dropped by more different people, from more different styles, than I can possibly remember. Don't remember ever saying afterwards, "Hey, what lineage is that from?"

But you know, maybe if I had I would have been hit less.
