I don't know anything about that game in particular so what i say may or may not apply.

They say that you need 10.000 hours of practice to master something. Anything. 10.000 hours is roughly 10 years.

I played league of legends and chess for that amount of time and still sucked. The reason i didn't improve is because when they say practice, they mean hard work, which is different than just playing around.

When i wanted to improve i spent more time analying my games, finding mistakes teying to figure out to fix them for the next time. Only when i had no solution i googled wuat othera did in that specific example. Another thing i did was look for chess and LoL guides, video explanations, spent 30-60minus practicing specific skills i lacked. I more about games itself, read ever patch of LoL, general important things about stages of the game, general strategies,... Lastly, i found a communities, played with them, exchanged advice and references, asked for tips,...

I did slowly but consistently get better, however, peronally, it took out all the fun out of the game and i don't have ambitions of becoming a pro player. So i stopped practicing and just continued playing for fun.amd with that, my progress also stopped.

I believe that all pros spent a lot of time practicing hard, and if you want to stay competitive you need to not only beat them in practice, but also find an edge anywhere you can.

I don't know if this reply is useful to you but i wish you find a way to break the plateau and continue growing as a player.

Thats not true. You can improve at anything.

You need to put more time and attention to what you are doing according to your limitations. Thats where good teachers and coaches come into play.

Its rarely a race. Often its a marathon.

I am at "I did," and i "can't." I did have a job, and i cant find another one.

Small steps.
