Well given that Essence Reaver is one of her core and rush items, her mana costs become a non issue after the first 10 minutes of the game, considering you don't feed your brains out in the laning phase.

After that with ER and Zeal you'll have enough crits to replenish your mana pool. What keeps her from being game breaking is her low base attack speed, forcing her to rely on her W to deal regular ADC damage.
