Her mana problem is actually intentional. Think about other ADC champions. The champions who has harass abilities( Caitlyn,Graves,Lucian,Sivir,Ashe etc...) are mana hungry. On the other side, the champions who doesn't have much harass ability( Vayne Corki and Kog'Maw[ These two before they reach 6] etc...) They intend to keep this harassing at low and tent to make them go 1v1.
