Kinda sounds like you tried Twitch and failed hard.
Besides, you have a support for a reason.
No I dont think they are weaker, if you look at item changes in season 3 your looking at a very significant buff. Items like BF sword and the pickaxe got +5 to ad. Lategame may have gotten on a pure ad scale anc. However, stats like armor penetration and haste have deffinately taken on a buff in season 3.

He's only good in MATH, not in practice. I am 100% sure these "Pros" are saying he's strong because of one major factor.
People are not used to playing against him.
Nothing in Season 3 Magically made him better.

Yolo-queue, yes, Twitch will never be good as Ezreal, MF, or Graves. But that is because you don't have reliable team mates to protect you, while in team play he will be an absolute menace.
all in all, twitch is fine, he is really good atm. i'd take him over corki or varus or sivir atm. putting him in middle of the road at LEAST. meaning he is quite viable
The simple fact he outtrades pretty much anyone *and* has an incredible lategame makes him a great pick.
Just make sure to ban Blitzcrank.
