I Worked Out How To Balance Yasuo's Passive

Yasuo currently has the passive of:

INTENT: Yasuo's critical strike chance is doubled, but the damage dealt by his critical strikes is reduced by 10% (25% on Steel Tempest).

Now with this, if you have 50% crit chance you will have that doubled to 100%.

My Idea

Link his passive to his E (increase it back to 4 dashes), this way each dash will give 25% bonus crit chance based on the current amount of crit chance he has.

If you have 50% crit chance

1 Dash - 2 Dash - 3 Dash - 4 Dash 62.5% -- 75% ---- 87.5% -- 100%

If you have 30% crit chance

1 Dash - 2 Dash - 3 Dash - 4 Dash 37.5% -- 45% ---- 52.5% -- 60%

This way it means Yasuo can have his passive but it requires him to charge it up in order to make it work, this also adds more skill to his kit making him need to combo in order to get the most out of his kit.

So his new passive would read:

INTENT: Yasuo's critical strike chance is increased by a bonus % linked to the amount of Sweeping Blade stacks you have.

Conclusion

This would allow Yasuo to then be re-balanced (maybe undo a nerf or two) and open him up to requiring more skill but allowing more counter-play and stopping him from being godly when he gets 1 item, but still allowing good players to maximise his potential.
