Destructible terrain?

Here's a thought that might be interesting either as a new gameplay feature or "extra mode". Why not add the possibility of destructible terrain? It would make this game more "realistic" and offer more strategic options?

Hear me out: Realisticly, don't you think it makes more sense for there to be some kind of impact on the terrain? It's a battlefield, there's no way in some fantasy, you see this walking mountain crash through the wall?

Say you play Malphite and you hit your ultimate "Unstoppable Force" and use it through a wall, if the wall isn't stopping the force, then shouldn't the wall move out of it's way? Obviously, you don't give this to every champion, but maybe something could do? Maybe rework? idk, just throwing ideas here. It could also have some strategic values? Maybe even someone who could destroy some walls or cause damage to it or do some effects?

Maybe an idea for next seasonal changes to wow us? Imagine even if the brush doesn't stop the stealth, but the brush looks damaged until the end of the game aesthetically?

While I'm on the subject of champions interacting with the environment, but could you please add some water splashes and more of a visual effect to see the champions actually walking through the water?

I can't be the only person to think something like this. Upvote this maybe, pls? It be awesome for some kind of Riot feedback on this?
