Maybe a better Rammus' w?
Ever heard of that story of a guy that shot an armadillo which resulted into the bullet ricocheting and shooting someone else? What if Riot could upgrade Rammus' mechanics and visuals on his W to something similar to the story.
For example, Rammus E+W to enemy ADC, enemy ADC AA, AA hits Rammus and makes a visual ricochet and hits another near by enemy. The ricochet visuals could be similar to Sivirs' W, but it only ricochets once of course. I also felt like some of Rammus' skins could interact with this mechanic. For example, a Sweeper Ramms soccer-ball or a Ninja Rammus shuriken bouncing off from Rammus body.
Not sure if the ricochet could hit just the attacker, a near by enemy or both the attacker and near by enemy. Also im not gonna get into how much damage it would do because I dont know anything about balancing :^)
Not sure if this has been discussed before, but I wanted to bring it up just in case :)
