Best used if the enemy team has 2-3+ champs that rely on autoattacks for the majority of their damage output (or for instance, the enemy AD carry is superfed and is the main influence in teamfights). It's situational, but not very situational as you put it. Commonly built if the enemy is going for a double AD carry meta.
