Twitch isn't really overpowered. He's a one-trick pony. People just freak out when he pops out of stealth. A stun or blind or knock-up usually removes the threat of his Spray and Pray, and he can be dropped in three or four hits. Just make sure your team knows to go after him as soon as he pops out of stealth.

There are also plenty of champs to start playing if you're worried about Twitch. Tryn, Ryze, and Teemo are all awesome anti-Twitch champs. Anyone with a decent stun (Ashe, Sion, and Eve, for example) can also drop without too much trouble.
