Expert take
Twitch is an excellent choice when you are willing to play around fight timing rather than duel ego. He requires real discipline: surviving an sometimes uncomfortable lane, reading vision timers, waiting for enemy crowd control to be committed, then appearing when the enemy can no longer reposition. He is not an ADC you pick to win every trade from the first wave. He is a champion who can turn one good reveal into an objective swing, especially with Blade of the Ruined King, Runaan and his ultimate. If you want to carry through positioning, patience and teamfight conversion, Twitch has huge value. If you want to force without reading the game, he becomes a free target very quickly.
