It's not worth changing.... your cause is one of little importance.
THIS is not the kinda thing I want the development team wasting their time with, especially with how little it gets used and the other fact that it takes 2 players to take advantage of it.
And like I said... it's not only leapers... it's also sorcs... hell... jump on a sniper and shoot someone close to the edge. You're wasting your time on this one. Not... that... serious.
So what would you suggest then? Have Bioware put force fields around the gap too so the leapers can't get across? because besides nerfing force leap that would be the only option.
