Syndra's Q only lost 34.5 Damage to champions.
People have complained about Syndra's Q damage nerf and how it takes 3450 AP to equalize it with the old Q's damage. This is TRUE. What is not taken in account is the low difference of AP scaling between the two abilities. Old Q ACTIVE: Syndra conjures a Dark Sphere at the target location, dealing magic damage to all enemies hit, which then remains for 6 seconds. MAGIC DAMAGE: 50 / 95 / 140 / 185 / 230 (+ 60% AP) TRANSCENDENT BONUS: Dark Sphere deals「 264.5 (+ 69% AP) 」magic damage against enemy champions. New Q ACTIVE: Syndra conjures a Dark Sphere at the target location, dealing magic damage to all enemies hit, which then remains for 6 seconds. MAGIC DAMAGE: 50 / 95 / 140 / 185 / 230 (+ 70% AP)
As you can see, there is only a difference of 1% AP scaling difference between the 2. That means that the damage lost is only in the base damage, 34.5 magic damage, additional AP reduced the difference by 1 or 2 damage.
