Ideas On How To Sate "OP" Champions

We all know that many champions are extremely strong and can snowball. But the community does tend to hate on a lot of the champions for being called, "OP" My idea today is to come up with variations to help sate those people with champion shifts. A little idea, one that I had a year ago, is to give each champion a debuff along with their kit. Still working on it.

But allow me to get into my individual concepts

Yasuo Pretty obvious. The community hates him because of the dps and fighting power he has alone. I'm also a Lux player and get frustrated in matchups, seeing how hard it is to play against a Yasuo. Here's my concepts

Yasuo's passive gives him 2x critical strike chance. Something to do is remove that or add in something else, such as reduced critical strike damage. Players also face complaint on how easily Yasuo can move around. A way to help with this is increase the dash cooldown, from perhaps .5 seconds to 1 second

Darius Most of the community should know. Darius is extremely strong in teamfights as he can build full tank and still dish out high damage What people hate about Darius is two things: His Healing and his ultimate

For Darius Q, reduce the healing and put a bigger cap, so he can't heal a third of his health each five seconds, assuming cooldown reduction isn't in the picture. If not this, reduce the healing to perhaps 12% to 8% and have a flat cooldown, such as 8 seconds

Now for Noxian Guillotine. The reset is extremely annoying, as he can have his ultimate up, perhaps each time he needs it. But another thing people hate is his increase of damage. Each stack increases the damage by 20%, and it can stack to 5x, which is 100% increased damage. It's a very unique concept, but one that still is perhaps too strong. My solution is to reduce the increased damage to 10% or 15%, and keep resets, but make it so the mana cost stays

(Keep in mind, these are all situational and not all would have to take place)

Nasus This one is simple. Nasus is a strong fighter that builds extremely tanky, and is rewarded for farming. Here is the hard part: his passive. Nasus is extremely strong in fights because of his ability to heal off a lot of the damage he takes. The solution is to either remove the lifesteal, (bear with me I know this is a lot), or reduce the amount he can lifesteal in combat or in general

These were some of the champions I know stick out to the players of League of Legends tagged as, "OP" Comment if there are any others i should put into consideration
