I'll just clarify something from W: Riot is not taking Silence from champion for the sake of it, but because those that were taken from had enough damage to burst a target down even before the disable dispelled, hence why champions such as Viktor, Talon and Kassadin had their CC removed, Riot is only maintaining it in champions that doesn't burst within the CC's duration, be by sustained damage (Fiddlesticks, Garen and Malzahar) or unintended to scale late-game with offense, although not impossible to do (Blitzcrank, Cho'Gath and Soraka).
