tbh, i really think they should flat out revert the q nerf. no "compensation buffs", no added utility, just revert the damage nerf and have her be the lane bully she's supposed to be. i don't know which champions did rito think were seriously struggling against her or being pushed out because of her, but that simply did not happen.
she still gets a nerf to her reliability and her skillfloor raised a bit by having a tighter stun hitbox (mind you, morgana's sion-sized q is still untouched for some reason) and everyone's happy
syndra is a cool champion with fun mechanics that can be outplayed in many different ways unless you're the adc and try to 1v1 her, in which case i refer you to the whole class of assassins and burst mages that can do the same.
just revert the nerf, rito, no hard feelings
