Technically this wouldn't be an issue since you need a target for all jumps and you cant target through walls or get to places with no enemies on them. Exception would be elusive jump but this one could just be excluded from the changes and considering the horizontal movement of the animation, it wouldnt make sense anyhow for elusive jump to ignore terrain.
I get that reasoning but just as they made certain mechanics able to ignore hallowed ground of PLDs, they could just do the same for jumps. Also the majority of wipe mechanics dont have targets available the moment they hit, so jumps couldnt be used.
Really more playing devils advocate here more than anything, i think jumps are fine.
