It is a rush item is because the second ability people max as an ADC is. By the time is finished, people will be ready to reap the bonuses from the ability as soon as possible. The sheer chasing potential of the ability is quite terrifying if you utilize the movement speed bonus, but it's essentially useless if she decided to rush lethality--since minion damage can easily take it away.

The sustain is most important in the laning phase. will not be dealing the pokes she can't deal with the enemy pokes. The lifesteal may be "good enough" but when you rush lifesteal, it's completely irrelevant. As you said, is the most powerful spell on her early game, but do you really think she is going to be casting a critical  at 10% health? She needs to effectively zone the enemies in order to even make it possible and strong lifesteal is critical to that, especially when it directly transitions into.
