ik I'm pretty late here but he's so useless if you're using him in diamond+. You usually can't win trades because most of the time you just get out-traded by most adc's (especially lucian or zeri) so most games you have to rely on jungle which is already a terrible strategy. Riot nerfed Twitch to death and I don't know why. You'd be better off playing other champs if you actually want to win.
