Life per Kill

A common modifier on weapons in Diablo III, Life After Each Kill grants the player X hit points per monster slaughtered.

Leech will not be found in Diablo III; not at all, or else very rarely. In its absence, properties like LAEK will likely be quite useful.

It's not clear how this one will work for melee characters. After all, this bonus overlaps with that granted by health orbs, in that both will help refill your life, but only after a battle ends. That's nice, but the danger will come from potentially dying during a long battle with a tough enemy; LAEK seems like it would be useless against bosses.
