I think this game is balanced and fun
I am serious. I do not like these "Upvote if you hate _____" posts that just bring hate and offer no discussion. When somebody gives their sincere opinion and reasons, they get shot down. This post may be downvoted to the bottom, but I hope that the people who see this will think about what I'm saying.
I think that this game is balanced because of the great variety of champions. One champion can never be made completely obsolete by another. Every one is unique. Even with all the newer, complex champions, old ones shift back into the scene. Nunu is a recent example of this.
I like new champions because they don't shadow or overtake the existing ones. But they interact with them, and add more depth to the game. For instance, Ivern can sprout brush, which can be used advantageously by champions that utilize it like Rengar or Garen.
There is a lot of talk against plants, but trying it out firsthand might change some minds. If it's not good, the developers will listen, and they will change or remove it.
It's because of this diversity in champions that make this game fun. Along with the changes that come every patch which keep it fresh. Stay open to changes. After all, that's why you play a game in the first place, to have fun.
Some games are not easy. Sometimes it feels like the enemy won already by champion select. Some of your allies lose lane. Some enemies camp your lane. Someone afk's. Some promotions are lost.
But remember why you are sitting down here, staring at your monitor. Why are you doing this? Think it over as you are in Queue.
Good luck have fun.
