Twitch needs an attack speed growth nerf and his stealth duration reduced by 2 seconds at all ranks
The long duration of his stealth in lane gives him way too much safety and zoning potential, and at later ranks way too much safety in team fights.
People need more chances to catch the rat because right now his laning is way too safe for how well he scales into the mid/late game. People also need better chances to spot him out during team fights before he can ult and unload. RIght now Twitch is basically the Master Yi of ADC except that he has 850 range, and doesn't even have half the risks that Yi has to take to 100-0 a backline.
