Heroes of the Storm uses ragdolling when it comes to characters dying, which can be pretty comical at times. But would it be appropriate for League?
I know you won't add it, but humor me for a bit.
watching 
go flying across the map would be a nice sight
Ragdoll deaths should be in every game. Even in cutscenes. Imagine if sephiroth stabbed aeris and she bounced all over the room.
The problem with ragdolls (and all phisics in that matter) is that they are very memory expensive, and league is known for its low requirements.
TBH I wish they would, that's one of the many reasons I love HotS because when I kill people their bodies ragdoll across the world.
