I solution to the "Vayne plague" and a idea to improve Yasuo's Windwall
For those that are fed up with seeing 
in virtually every match, in the jungle, top lane, mid, or her normal bot; I have a solution that should fix the absurd problems with Vayne dominance and also setup a future mix to avoid problems pertaining to %-health damage. Also in this post: "a fun rework to Yasuo's W that will promote more dynamic gameplay for everyone".
Vayne's E Silver Bolts is the problem it deals true damage that scales with max HP; I get it, its meant to be a tank-busting ability, however it ends busting everything. We need to address its impact on squishy targets while still allowing it to shine against targets like juggernauts and full-on tanks. My proposal does just this:
Silver Bolts: Every 3 attacks deal ((50% of enemy armor) + (4/6/8/10% of total bonus health)) as true damage.
Comments: Those calculations seem odd but essentially at rank 1 of her E, it will deal 50% of the targets armor after 3 hits, and each rank afterward adds 4-10% of the targets BONUS Health ( notice its not TOTAL HEALTH). This change means against say a mage who builds glass cannon with no extra health but 100 armor from Zhondya's, Vayne will deal 50 true damage against, but against a tank like say Taric: +2000 bonus HP + 400 Armor = 400 true damage and 200 when his bonus HP is gone. As you can see the effect gets exponentially more powerful against a tank but it's damage is almost non-extent against a squishy target. This distinction will help stop the situation where Vayne kills everything with her E.
The way %-based damage will be dealt now, not just for Vayne but also 
, 
, and any effect the deal %-based damage will scale off of bonus health gained through items only. Also, when that bonus Health is depleted the bonus damage from these effects will cease to functiion on those respective targets. This will mark these items as situational option not an "auto-buy" for any situation.
That is enough Vayne/%-health talk, lets talk about the bonus Section: YASUO's WINDWALL.
Yasuo's Windwall is what we could say "toxic" for opponent, alot of people hate Yasuo for this skill. It denies the idea of a skillshot with a giant wall of "NOPE". It provides no interaction for the enemy players; and as I mentioned in a previous post, it is poorly designed because of that 1-sided interaction. A nerf won't be a good change, but a rework might lead to something extraordinary and fun. Lets do fun, eh?
In my rework idea, Yasuo's Windwall doesn't absorb projectiles but instead deflects them based on the angle the projectiles hits the wall. A projectile that is deflected would take on the neutral properties of a jungle minion allowing Yasuo to gain assists by saying deflecting an enemy  's ult into say their allied 's face. On the other side of that, an enemy  of Yasuo, could use the wall to ult into a inconveniently placed enemy champion by say 'bouncing' off the wall. The shape of the wall would change to a curved "C" shape with the opening part pointed at Yasuo. To address the issue of "point-and"click" abilities, there would be a maximum distance set for deflected projectiles with no skillshot in them to say an extra 500 units after being deflected.
This change would open interactions on both sides and allow fun gameplay that both sides benefit rather than just being a dead "NOPE" skill. Yes this also means Yasuo and his allies can deflect off the wall to so Yasuo could his tornado off the wall to hit an enemy just off to the side and then ult.
