Tear of the Goddess was in Karthus' Death Note along with just about every other removed item - so it's possible that "balancing for Manamune" isn't necessary.

As for the core idea, I've always been sceptical of "bouncing off terrain" effects simply due to how buggy Riot's terrain-edges are - they aren't really suitable for geometric calculations. Although that may just be me rationalizing, since I'm never ususally against ideas due to current limitations. On Ezreal specifically, though, I don't think I like the idea. Even a bouncing linear skill shot is just another linear skill shot - the point is trying to give him a different way to express himself. Think of the issue like Cassiopeia's rework - the reason her W was changed is because it has the same use-cases as her Q, so she basically had two copies of the same ability. Ezreal's Q, W and R are already like this, making one of them bounce won't change the fact that in most cases he's just gonna fire them all in a straight line.

P.S. That's not to say I'm actually 100% sold on my own idea, but the direction I took was to try and preserve his "spam spells in a straight line" by making it his innate ability, and then giving him two new spells with hopefully different use-cases.
