Suggestion for champ ult

There is one single mechanic that i've always wanted to see in league.

Bouncing projectiles, not like a zac bounce, or heimerdinger grenade, i mean like it flies straight, but will bounce off of walls and terrain until it hits something, whether or not is goes through minions is beyond my shit giving. But if a champ with a bouncing projectile ability (preferably an ult) came out, id be very very happy!
