Guessing Riot does not care about Syndra at all
Passive change (Q sphere lifetime 8 seconds, W can pick up 2 spheres near the target, E/R unchanged)
Dark Sphere (Q) AP ratio increased to .75 from .6 Scatter The Weak (E) cooldown lowered to 16/15/14/13/12 from 18/16.5/15/13.5/12
...
If anything, the passive forces Syndra into maxing Q first into W and eats a lot of her damage (unless her W does more damage per thing carried or something) and semi-utility on W slow increase.
Also among the only mages without new icons with the update (just a note; I don't really care about this).
Meanwhile, full scale kit updates on every other mage...Except Lux.
