Sona With PD?

Sona can build PD without problems (mostly mid)? The item can proc PC W + Passive and it will reduces a minimum 37% damage of the enemy in yourself. And the PC W scales 4%-100ap, so if you have the normal build to mid Sona (Lich, Ludens, Morello and Rabadon plus Phantom Dancer) you'll reduce 59,4% damage of the enemy in yourself. I'm not english fluent (i'm from Brazil) so i'm sorry if that text doesn't makes sense for you. PC W = Power Chord of W, Staccato
