User blog comment:StrategicMagic/Carry by Proxy - Why (Some) Assasins Don't Fall Off Late/@comment-99.3.5.40-20121209082527/@comment-5194571-20121210105320

Instantly removing the AD carry while dying yourself is a worth it trade. That's where the "lifebar tank" idea came from. Damage wise, I'm removed from the fight. But not phyically. I can't do anything for ~20 seconds (LB ult has less than 30 sec CD at rank 3) anyway, while their AD carry could put out sustained damage over the course of the fight. Just being able to be a targets is what makes it so that I'm not actually removed from the fight. That revenge kill on me can be the reason the enemy team loses a fight. Sure, champions like Orianna can do more in a fight, but this is mainly in defense of those people that pick assasins like Leblanc. Leblanc doesn't have a 0% pick rate worldwide, that is what this blog post is for.
