@Meddler: Don't you think Syndra needs a small buff? I'd go with mana costs.
Ever since her last Q and E nerfs, Syndra's been a rare sight. Her stun is unreliable, and her early mana-to-damage ratio for her Q is absolutely awful. Granted, she needs to have worse early power to offset her powerful late-game, but at such a mana cost?
Would lowering her Q's mana cost a tad at all ranks break her? I don't think so. The last patch removing the +3 mana regen masteries kinda hurt for her.
