For 25 BP, change somebody else’s username. Sure it’d be one hell of a griefing vector, but only if anyone’s willing to invest that much in their prank.

Also 3 BP for a one-day ban from flamebate, though they’d still be able to post with alts.

Another awesome prank would be getting to see who somebody’s alts are. Just think about how much that would crush certain people.

And since the admins have done a bit of klan renaming, that could be a new one. 1 BP for a klan’s admin to change the name, 2 BP for a member, 3 BP for anyone else.

As for BP impacting gameplay, that really should never ever happen. Making ep2 cost 7 BP was bad enough.
