Syndra's design is STILL abject garbage...
She's built around her Q. The Q itself is fine, but the rest of her kit is based on manipulating her Q further to do damage.
The problem is her W is slow and unresponsive. The game always has to sit and think for 2 seconds so it can register that you grabbed an orb/minion/monster, and then it has to play the throwing animation for another 2 seconds, lock the animation clumsily to the hit box, and by that point your opponent is across the field doing other things.
Her E is great in theory, but the positioning required for a 1 second stun is ridiculous when you have so many other champions that have point and click stuns/roots with themselves as the pivot point, rather than pivoting on your orb as Syndra. Having to play around a stationary object instead of yourself is incredibly unfair.
How could Syndra be fixed?
For one, her W's code should be looked at and the cast time on both steps lowered for fluidity, especially in this fast paced damage meta.
Second, her E should be reworked into a better slow and knock back for the wave so it's less dependent on having an orb.
