I'm done playing this game. and I will tell you why
Its not efficient, at all. Even if you play well by any measure---good farm, good KDA, you get objectives---the only way to climb is to be at such a high skill level that you can consistently carry the sacks of shit that will inevitably be on your team, or play the most broken or OP champs to make that carry process easier, or even possible.
The game doesn't reward very good play. It really only rewards ridiculously good play or extremely bad play (when the enemy team is just so bad its almost impossible not to win).
So the amount of time invested is not worth it. Its not fun when the way to win is so narrow, and your choices for champions dissolve to a handful. The game isn't fun, and it hasn't been fun for quite a long time.
Also, its innately toxic because it plays on human nature. As I have said before, and morons argued against me as usual, people don't do well when they feel powerless. It makes us frustrated and angry. Its quite irritating to have your personal rank be effected so severely by so many bad players on your team. The game makes people toxic. It literally couldn't do a better job of bringing out the worst in people if the game was purposely designed to do that.
This is not worth my time. You are better off playing Magic The Gathering, at least you have face to face interaction and you win or lose on your own merit, not because you got paired up with some random sack of shit.
This game is one of the worst things to happen to humanity, much like Facebook. I advise all of you to reflect on you life, what is valuable to you, what is efficient use of time, what is fun...and if you come to the same conclusion, uninstall and post that you are and the reasons why and encourage everyone you know to stop playing as well.
The game is designed to be addictive and frustrating to suck money out of people. Wake up, and stop playing. Riot can go to hell.
