I know I'm probably the 2,643,123rd person to make a "we need a replay system/demos!" post. But I've got one more reason to add to the list so I'm throwing in my 2 cents.

I've been playing a ton of Yoru lately. And I think he has a ton of potential to manipulate rotations with his Fakeout (footsteps) ability. It's one of those abilities that heavily rewards game sense and game knowledge and I think that's super cool.

The only thing is, most of the time, it's hard to tell if your fakes actually worked and if the footsteps you set up at the beginning of the round actually drew rotations. With a replay system, Yoru players will be able to analyze the effect/impact of their plays and hence, significantly improve as a player because of it.

I know Riot's already working on a replay system, but my hope is that the Yoru main on the replay development team will see this and know that the earlier replays get out, the faster they'll hit Radiant.
