This warning does not protect us from anything.  Once upon a time it helped loot get to the right people, preventing accidental pickups.  Because of the two hour trading timer that protection is no longer needed.  When soloing this warning is without purpose.

In the meantime, the BoP warning only harms us.  It takes time.  It distracts.  It can cause you to lose items.

"This item will bind when picked up" was once a useful piece of information.  No longer.
