Judging by her ratios, looks like she'll be an even better AP mid than Janna and Lulu.
High CDs you say? np, she has insane utility on all her spells (+ her passive applying on all of them), and all 4 of them deal damage. Ultimate and Q also have decent ratios.
Her supportive side looks pretty broken, and they give her damage and decent ratios on all her skills ugh.
