My concept to make Riven less frustrating

I find Riven fine personally. See my post explaining how bloated kits are normal now. But here is how I would change without touching animation canceling or her gameplay design. To appease the complaints of the boards.

Q, THIS is Riven's attacking move, not her E. IT should not be as strong for escape. As such I propose this change. Q Cooldown increased by 6 seconds with a 1.25 second delay between uses, damaging an enemy champion, minion or jungle monster with this ability lowers the cooldown by 2 seconds and nulifies the delay. If all 3 hits are used offensively, cooldown ends up the same.

W, Unchanged.

E, Valor isn't a problem for escape. It is primarily her disengage tool. That is what it is for! As such, the change will be to how much uptime the shield has. Lasting 1.5 seconds the shield is already short but is rather big. It exists primarily as a sort of 'timed block' for incoming damage. A skill based mitigation. This should be made clear thus I would make the shield instead last only 1 second. Making it more clear this shield is a tool for momentarily invalidating enemy attacks rather than just a huge ass shield. I considered making it .6-1 second based on rank but that made shield leveling too valuable. It also makes it easier to waste the shield.

R, Unchanged.

Base HP regend buffed by a small margin to recover lost lane sustain. Base HP buffed slightly at early levels to recover lost laning survivability.

Thoughts. Suggestions. Post below.
