The real reason why I don't enjoy this game as I used to enjoy before:
The loss "strategic" pleasure, the feeling of outsmarting the opponent rather then outplaying them. Back in 2013~2014, I had fallen in love with League. The idea of playing a huge multiplayer chess game with 80++ different characters and some action in the middle was very exciting for me. I got completly addicted, not only for months, but for years.
But now, whenever I win, this satisfaction isn't nowhere near as it was back in the day, not only because of exhaustion, but mainly because of how the game focus drastically changed from strategy to action, to the point where champions move like fighting game characters and everything is about 'top playz'.
I miss the old LoL...
