Idea for an Assault legend

I feel the ability to gain height and drop from height is too easy, it's just an ingrained mechanic that people do naturally and pay no mind to. The advantage that high ground gives you in an end game ring situation gives the team on height a significant advantage because all they have left to do is drop down and clean house once they get some free damage.

I think a legend that counters vertical movement by enabling fall damage would be interesting and would force you to think about the consequences of vertical positioning. Obviously the advantage of height is usually earned through positioning and rotation so I'm not writing this as a complaint, it's not an issue that needs fixing, but I think it would be interesting to consider an "anti movement" type legend that makes players think twice about what might be considered a "god spot". Especially now with the addition of so many vertical movement abilities (valk, revenant, fuse, alter, pathfinder, octane, horizon, ash, vantage, loba, newcastle). The ability to gain height fast is mind numbingly easy. 

Maybe the ability would be like an aoe ult that increases the gravity in a certain space for all players. Could just be a horizon rework honestly. Or maybe like a seer tac type ability that imposes increased gravity or fall damage onto one player for a short period called like "boots of iron" or something, more like a high skill timing type ability. The legend could wear heavy **bleep** boots but since their legs are jacked as **bleep** they would run the same speed as everyone else except with a passive that does damage to players that you jump onto.

 Idk if any of this could be viable but I just thought I wanted to get this idea out there somewhere.
