About the Rift's river

TL;DR: River doesn't start anywhere, and needs channels to look like it's flowing off the mountain. Would be really cool.

With all of the cool updates and interesting origins for dragon and baron, as well as adding off-map stuff, I was actually kind of sad/interested to see that Riot didn't include the origin of the river.

The river just kind of flows on top of the mountain, and then it drops off a cliff on both sides. Are we changing it to just pools on both sides, or are you going to add something in that makes it fit better with the map?

I really am not trying to nitpick or anything, but I feel like, while it's on the PBE, you guys could give it some thought and make something really jump out and wow us. Like maybe the river wells up from ground water in dragon and baron pit and then flows off both sides, or maybe because it's constantly raining in east blue jungle, the river comes from above dragon pit from magical rain and puddles for example.

On the other hand, the river kind of disappears at the end, instead of falling off the mountain. I feel like some cohesion could be added as far as adding some stone channels or irrigation meant to redirect the river so that it doesn't just look like the water disappears.

I would love any kind of response, especially from a Rioter's stance on this, but give me your thoughts. :3
