Ok so Riot only notice these problem in Clash but not in Solo Que, CLASSIC

1. Match Making Balances
2. Rage quitter
3. Smurfing
4. "Hostages" etc etc etc

2 thing most player would complain about is: SMURF and OP CHAMP

First things First, I'ma say all the words inside my head I'm fired up and tired of the way that things have been, The way that things have been,

Complaining about smurf is a dumb issue for Riot to solve, because anyone that loses their game would just point their fingers at "SMURF"

Second thing second, Don't you tell me what you think,

OP Champ? Any Champ can be OP, there are some definite OP Champ but yeah any "CHAMP" can be "OP" or consider OP base on how the game is going

How to make a Champ OP, isn't all by the BUFF Riot gave them To make a Champ OP, get fed and more IMPORTANTLY

GET GOOD

Last thing Last, Don't have too much high HOPE,

League is unbalance and will always be unbalance, Your feedback and Your complains, they're all pointless unless you can think and say what Riot has already have in mind of fixing already and ready to share their thoughts on it.
