Where's the bounce in Let's Bounce?

The ability could easily be: Zac spews out goo dealing damage in an AOE and knocking enemies up on the first hit of the damage etc etc.

He may look like he's bouncing, but he can't time his leaps during the ability to jump over small walls - or any walls. At the very least he should be able to bounce over player terrain i.e. Jarvan's cataclysm. It sucks when poor Zac is excluded from Jarvan's party since he can't bounce over the wall to deal damage.

I can understand that being able to bounce over the same wall 4 times may be a bit much (though I think it'd be a fun thing to add/create some interesting gameplay), but he should definitely be able to bounce over player created terrain if he's at or close to the height of his jump. For the sake of clarity it's confusing that he can't, and I don't think it'd be a buff that makes him OP. Thoughts?
