Real Water in the River
On the new Summoners Rift, it should be made so that the bottom part of any champion walking through the water in the River is shown as underwater. This way it would appear as though the champion(s) are wading through the water, as opposed to simply running on top of a blue surface. Also, if you (Riot) could also please add some splashing effects based upon the hit-box and movement speed of whatever is running through it, that would be so very cool. Thank you, Riot.
Sincerely, someone who is actually named River.
