The reason of current player frustration with the game
Is that League of Legends has fundamentally changed in the aspects that were the primary motivation and reasons for veteran players to play and keep playing. League isn't the game we've enjoyed anymore, and Riot has made the conscious decision of changing it in ways that appeal to a larger, but different audience, which just happens to conflict with the motives of veteran players.
That's it, guys. The game won't change for the better. All that remains now is that we quit and hand over the game to the casual players who enjoy 20 minute deathbrawls. We've been surpassed by the next generation of gaming.
40 minute strategic games with personal skill influence and unbiased matchmaking? How would your average casual player enjoy the game if he'd lose >50% of his games? Investing time in video games so that skill development is eventually a reward? Grow up.
What's our motivation to keep playing? Still hoping that League will return to its former glory?
It won't.
I pity the streamers that are basically forced into streaming League just because their viewerbase hasn't changed. It's obvious that the majority of popular streamers are not in it for the game anymore.
But hey, LCS is great, right? .. Right?
