So I just had an ememy Vayne tell me...
I was shit because I couldt "1 shot her" by "just pressing R" on Syndra.
...
Like, isn't that a good thing? Both end game builds, she had Merc Scim and I had Void, SS and Liandry's. She QSS my stun and survived a 6 sphere R (barely).
See? If you get MR vs Syndra, she cannot just "press R" and kill you. And if she cannot just "press R", then she is shit (apparently).
