I'm actually glad Riot has approved Tempered Fate (Bard's R)
2012 Riot wouldn't have allow a Dota-esque ability like this (Naga Siren x Faceless Void) because they thought the community would be too immature and would troll more than use the ability as it was intended to be.
Kalista was the first champion to "force" a champion into an action they have no control over, and I suppose it's a good omen that most of the player base has proved themselves mature enough to not use this type of ability for griefing.
Digression aside, this could open up some new fun ability designs in the future. Faith in League - temporarily restored.
