I ask because some of my guildmates say there is, some say there isn't, and in my personal experience, I've been garroted followed by strangulate and it felt like an eternity before I could cast again. But in the heat of an arena match it's hard to tell.
So do silences suffer from Diminishing Returns like CC does or do silences always last full-duration (sans talents/meta) even when chained back to back?
