Is Sion weak against Vlad?

So I played too horrible games as my main last night. One was a top (I kinda just sand bagged the lane because I couldn't touch her) and the other was .

Now I hate in general. I hate his Q, which is basically the neighbor who goes into your house without asking and grabs some sugar when you are on the can. It dealt (and this is probably because is squishy) a huge chunk of damage with thunderlords, making it near impossible to farm. After a gank from his jungler (Vlad got first blood from a failed invade) he had enough power to tower dive, and tower dive he did. It was pretty much impossible to stop him.

Now I will admit that I played Sion horribly. I like to think I was so focused on the new Skin's flashy animations in my previous games that I had plan old forgotten my playstyle (not having league for 4 days might be the cause of that). And after losing a game where we lost every teamfight to a ult, I guess you could say I wasn't in the best mood when I told my team, "Vlad's presence tilts me" (I do not have a good track record with Vlad).

So was this just a bad match up for Sion, or did I just play horribly (I know I played horribly there is no denying that. But playing horribly on a champion that mine is weak against makes me feel a little better).

Sigh...this whole endeavor makes me embarrassed to have over `130K mastery on Sion. Makes me wish I could reclimb the mastery curve.
