What is your objective when you enter a solo queue?
I left LOL for a few months to play Apex and after coming back, I see things much clearer than before when I was playing only LOL. The players mentality in Apex is so much more different than LOL. It's like they join a match, and their sole purpose is to help the team, play with the team, and win with the team. Even if it's a loss, it was still a good game.
After coming back to LOL, I notice how much better I play because my focus is on helping the team. As I continue to play, I see my skill gradually go down because of some players just aren't in there to "work" with me, like they just do their own thing. I would ping OTW to gank, and my laner would just sit there. I leave bot side jungle and ping bot to be careful, they shove to turret and get ganked.
Simply put, it seems like a lot of LOL players join solo queue and tunnel vision into their own mind and plays. Ironically, they blame others for making bad plays.
So if your objective in a solo queue is to not work with your team, and rather be toxic and blaming, why do you even play this game? Your sole object should be "Okay we're in this together, let's work together and try to win". If the team team is urging to you group, you should group, or else, why are you in this match with them?
Anyways, a lot of LOL players need to stop playing LOL and play other games. You'd be surprised at how much more clearer the view is when you come back.
