Try and play those characters you nerfed and see how "balanced" they are. If you played Twitch for the past 3 nerfs you wouldn't nerf him those 3 times.
Twitch is still good. Stop building him full AD items and put him in a team where he'll get support.
You must have missed CLG's game with jiji on Twitch the other day.
Twitch is fine. Stop using Ambush as a "omg they can't see me lolol" and stick with your team.
