Broken Champions

Okay, so these Champions are the most powerful and need-to-be-tuned Champions in my opinion. Here are the 4:

Garen - Garen is a super tanky, cheap Champion. He has a lot of damage WHILE he buys only Sunfire Cape and Deadman's Plate. His ultimate does so much damage, and at full level his ultimate has a 60 second cooldown. He's got a lot of damage scaling abilities and has lots of speed buffs from them. Garen can beat really any Champion in top lane, for even when they poke he uses his W, reducing some of the damage and just healing it up with his passive. But really, his cheap price with such powerful abilities really needs to be tuned.

Riven - Riven is so powerful, with her abilities scaling off her damage in a giant way, with her Q being able to be activated three times. She's got so much mobility but doesn't use mana. Her ultimate does so much damage, even though it's her only poke. She's got a knockup and a stun, which is really annoying. She really needs to be tuned.

Yasuo - the most powerful and broken Champion, in all of League of Legends. He has got such spamability of his Q and E, having his E have a 0.2 cooldown at full level! His ultimate has a pretty low cooldown even though he needs them airborne, but with someone like Malphite or Xin Zhao on your team... Ai! He is the most played Champion, I get so many mirror matches with him. Whenever I play a game and there's a Yasuo on the enemy team I'm like: "well guys, it was nice knowing you." My friend is past Silver and he soloed the Baron Nashor with Yasuo... He was broken before, you just had to add more critical power to the game, didn't you Riot?

Graves - Graves was a pretty good Champion before the update, but now... His auto attacks deal SO many damage! The point of being a ADC is to shoot but not be shot, by not getting close to the enemy. But now, he deals so much damage close up, he honestly has an AoE AUTO ATTACK! I played a 2v1 with my level 20 friend against my past Silver friend and even though we won (Garen is just that good) he got aces without dying.

Anyway, that's my opinion on the current broken Champions, tell me what you think! I was also thinking about adding Katarina, because her passive is amazing, but she's like really delicate. Thanks for reading!
