Chanpions I don't like and why

First of all, I have them ranked and I feel like my list would be:

1. Darius

So about Darius I feel like he is hard to play against no matter what his build is and what his score is, he can always make a comeback even after going AFK because of how much he heals and how much damage he deals through his passive. I mean he's basically a juggernaut and the way he can just heal off of you after a trade you should have won against him he can just walk away with you bleeding with around 4-5 stacks of hemorrhage(passive) and you walk away with under half HP and then he can heal off of pots and his recent Q hit. It truly frustrates me and I feel like he's too strong with his kit and needs a decrease on ratio either to his passive or healing. Even when he builds tank his Q will still heal him for over 300 HP and then you get something like 200 damage to you and the only way to beat him is through full armor and HP regen.

2. Garen

With Garen it is hard to poke at him without range and even when you are ranged he can still catch up to you and then start beating on you anyways. With his Q comes a silence for I believe 1.25 seconds which is too long and I think it should be decreased to 3/4 or 0.75 of a second because then he has too much time to attack you and since his E will decrease your armor it will end up with you at below 60% with only one combo at level 2. At level 3 early game he has the ability to decrease damage income by 60% within just a couple of minutes playing. So you will end up silenced and low on HP while he walks away with over 85% HP even after turret diving with W. He is just hard to plat against and will win if he is full AD or full tank, either way he wins and that should not be the way any champion works.
