Ranked is Nothing but a Nightmare
Only recently have I tried out Ranked Games in LoL, as I mainly stick to Draft Normal and Team Builder... and the rumors I've heard are true... this is nothing but nightmare fuel. From people choosing Revive and Teleport so they can go feed the enemy team quicker, to people who AFK/Leave randomly, or when you ban someone's favorite champion and they go BALLISTIC and end up... feeding the enemy team... this is horrible. Now, I know these topics have been posted a million and one times but, damn I thought you people were kidding or they are rare circumstances!
The worst part of all is when you KNOW you have a troll right during champion select. Either the game starts and you have to waste 20 minutes, or you can leave and get a penalty and have to wait. You think Riot would figure out some solution to end this crap.
UPDATE However, I completely understand how difficult is to fix these issues. If you have a scenario when someone leaves because they are mad or DC, you should still lose LP. I know the community has mentioned you shoudln't lose any when this happens, however people WILL exploit this. Whenever you are about to lose, someone on your team could technically just leave to help prevent his teammates from losing a ton of LP. Not a great idea.
What about people intentially chosing stupid champions with idiotic builds for the sole purpose of trolling? Well, you will end up having a lot of matches not even starting because you'll have a few people who don't like your champion choice or they may think you are "beneath" them, ending up with a lot of people just booting someone for no reason.
While I don't have solutions to these problems, I do believe Riot should make it a priority to think of some method to prevent this from happening. I know attitude is cleaned up considerably in Gold, late division Platinum and Diamond, but a majority of players start in Bronze/Silver. Why should they have to suffer through these social insane people just to climb to a better elo?
