Why League of Legends is unbalanced

I found this post on this thread and it sums up why Riot purposely has champions unbalanced.

"Gameplay imbalances."

The reason for these, is quite simply to make Riot money. Look at how many people buy brand new champions as soon as it's released. If they describe it as overpowered, and show it as overpowered, chances are, people want to buy them so they can dominate as well.

If there's anyone who hasn't watched the latest Kayle spotlight, go do so. Look at how powerful they make Kayle look late game to the regular eye. It makes it look like she is an awesome champion. Until you realize she's level 18, and the enemies are mostly level 13.
Take any of the champions into perspective. They make them sound awesome to begin with. Ever so amazing in all of the champion spotlights. Most of them turn out to be far from it.

It's all a big marketing ploy. All of it. Everything Riot does, is to get money towards their game. Although, many who don't look close enough won't see it.

I've already put enough money into this game, so I'm afraid to put this game to rest in my computer. Then I remember all of the disadvantages of playing this game, as listed in the original post."

"In an interview, a riot employee said that that don't keep ever champ balanced because first of all, it makes it is more interesting. And also, because the op champs sell more, making riot money."

This is quite disappointing because Riot is more concerned about making money short-term and looking good on paper for Chinese investors rather than caring about long-term customer loyalty and value. In Spring of 2011 Riot was bought by the Chinese company Tencent, which explains why Riot is always releasing boring champions and skins, but not improving the game at all. Riot is just another greedy company that uses League of Legends to make money. Will Riot change to a video game company that cares about its customers and providing quality game play? I highly doubt it, they are too greedy and care more about Chinese investors more than anything else. I finally got sick of how Riot was running League of Legends that I haven't bought a champion or any skins for a very long time. Riot lost a customer and I hope more people would realize this and quit playing LoL.
