Thinking of picking him up, did well with him in a pvp. Still, i'd like to know how well i can do w/ a crappy team. I'm a good kog'maw but.... that's kiiiinda situational lol. --- Idealism is seeing potential. Pragmatism is seeing consequences.
Twitch is fun because you know even if your team is doing semi-bad, you can still change things around when teamfights start rolling. It really depends on your team composition and theirs, though. If you have a J4 on your team, I'd say go and pick Twitch. It's a really nice pick with J4 and most of the time, it never seems to fail.
Orianna with J4 works well. Add a Twitch in that composition and it works even better. Don't expect solo queue to build around a player, though...
Overall, Twitch is a good champ. He doesn't need as much support and peel as many might think because he's usually just in the back shooting away. You can't really touch him and if you get BotRK (if you really choose to), you can peel for yourself if someone comes after you.
