Yeah the silence is so useful in lane against melee casters like Riven (I kept annoying a Tryndamere I was against by silencing his spin out, was very fun to do)
Really unreliable to actually use it exactly when you want it in a teamfight though without flashing.
The first game I played I was against a fed Kat and our team was low on CC, if I didn't have flash I could never stop her ult in time.
