My friend. Let me tell give the best advice I can possibly give anyone.
Do like I did. Jump ship. Just get out of this sinking sesspool of a game and you'll feel much better.
I jumped shipped long long LOOOOONG ago when Riot began destroying the diversity and balance of the game by adding more damage. The damage is now utterly out of control and there's no way for them to repair the current state of the game, it to far gone. Once I realized that Riot had no intention of even attempting to repair the damage they have done to their own game, I jumped ship. It broke my heart at first because I played league for so long, it was a huge part of my life, but let me tell you when I moved on I felt way better in the end.
Right now, the team behind the current state of the game just doesn't care. They have no heart for the game, their passion for the league and their own work has completely run dry and it shows very clearly. Their drive to make the game fun, their determination and passion towards League, it's just... gone. They've lost it and I think at this point they know they have. When you have a team behind a game that just doesn't have that drive anymore, then you know it's done, it won't ever change, it's not going to get better and once you realize that and get yourself out and direct your focus onto other things and games, you'll see a huge improvement in yourself. You'll discover a new passion, new energy for new games and that gamer spark in you will be revitalized. I'm telling you from experience, just jump ship.
You can tell the team behind the current state of the game has totally lost their drive and passion by the patch notes as well. Just look at them, before we used to get detailed notes on changes explaining why they were being changed, why someone was getting buffed or nerfed. But now these days the notes simply read:
"We buffed this champ cuz proplay"
Or
"We nerfed this champ cuz LCS"
it's just the bare minimum these days.
Currently, I'm playing Pokemon Masters, it's a mobile game but its fun, just slipping away from league and getting into this was very refreshing and doing so gave me the energy to go out and try some new other games as well. Monster Hunter Ice Borne i hear is pretty good, why not try that?
I wish you all the best in whatever decision you decide to make. I miss league dearly but leaving it behind was honestly the best decision I could have made for it. Whatever you choose to do, I hope it works out.
