At this point you're just reaching. I've been watching Lux's and Annie's decimate teams for years now. Syndra ults one person and if she doesn't have a team to back her up she gets wrecked.
Annie is literally listed as good beginners champ for mid. She's super easy. You know who is the next listed champ? Lux. You know who is not recommended for beginners? Syndra.
Syndra's Q, W, and E are skill shots and you can dodge all 3, but that would require skill and a fair amount of exposure to playing the champ. The only one that isn't a skill shot is her ult. But for to even get off her ult at peak she's required to use 2 abilities before throwing it.
The statistics don't match your story.
The listed skill caps on champs don't match your story.
You have nothing but conjecture to support your argument. It's just this belief that someones skill shots are harder to dodge than someone else's, which is just silly.
