My Ideas for Riven's Rework

Last I heard riven is currently under the microscope of the riot team who's trying out new ideas for riven, most recently they put out the riven patch on PBE that gave her a new passive that increases her damage by % base on the amount of edge she has which is a unique resource to her.Unfortunately I'm not a game designer so my ideas may be unbalanced in ways I can't see but sense I liked the idea I came up with I'll post it anyway and let you guys (and possibly some rioters) decide if it's a fools idea or the greatest thing sense sliced teemo.

Passive: Edge. (Yes this is the same name as the current experimental passive but I liked it so I'm using it) Every Auto Attack grants Riven 1 Stack of Edge up to a maximum of 5, Upon activation of an ability that riven has enough edge to empower the required amount of edge for the empower is consumed and the ability and it's empowered effects activate but once an empowered ability has been used Riven can not use edge again for a short time however she can still gain edge during this time. The CD on the passive reduces with points put into her ult going 5/4/2

I don't think i could create full tooltips as I'm not that experienced so i'll just give the best explanations I can.

Q-Broken Wings: Riven's third Q is no longer a knockup but instead a normal Q like the other 2 unless riven has 3 or more edge, With 3 edge Riven's third Q slows all near by enemies, With 5 stacks of edge Riven's third Q has an increased Dash Range and becomes a knockup except with a larger radius than it previously had. I also believe the CD should be longer

W-Ki Burst: First off this ability is changed from a 360 AOE into a cone in the direction that riven is facing, On cast it's no longer a stun either but it starts out as a slow scaling by every 1 edge Riven has (I don't know of a good % of slow to start with so I'll let you guys think of 1) but once Riven has 5 edge the ability becomes a small knockback roughly something similar to Vi's (I picked this because I imagine getting hit with a super charge blast of energy would pack a decent kick to it).

E-Valor: Basing it off of the name and ability Icon I imagine Riven charging valiantly into battle instead of doing a quick hop so that's why in my version of the rework I'm imagining it as a movement speed steroid while still keeping her shield except with a twist, Riven gains a large movement speed bonus + a large shield for the duration of the ability that works like her old shield and scales off of AD except the flat amount and the AD scaling are increased for every point of edge she has BUT during the duration of the ability if her shield is broken she is slowed by a large amount like Blitz's W. This ability now has a risk factor involved to getting a big shield and instead of the awkward little dash it's now a decent escape/chase tool but if you mess up and your shield gets broken the enemy of course can get away or take you down.

R-Blade Of The Exile: Only thing to add is for the duration of the ultimate riven gains 2 edge per auto attack instead of 1 and the ultimate ends after windslash is cast.
