Why does no one in game talk about a plan anymore?

After playing for ten years, my rank hasn't changed much, but I think I've improved a lot.

In season 3, I'd get Morg support, and they'd be ready with a dark shield the frame an enemy ability appears on screen.

Now, I get a Sivir adc, who can't time their own shield to block Morg's q. Ever, throughout the entire game.

Where's everyone's readiness to respond with the characters they choose?

Another thing I miss: actually talking with my team. It used to be that, 30 minutes in, people would start talking in chat about what we need to do to win that game. Maybe that would mean talking about when Yi should use q, or telling a teammate to wait for the enemy's ult before using their ability.

Nowadays, nobody talks to anyone. Nobody gives helpful advice in game. Nobody learns anything:

It used to feel like: you start the game, you're warming up, and maybe you can't time your sivir shield right away. By 35 minutes, now you're ready to pop that shield any time. You're getting together with your team. . getting a plan going.

Nowadays, I feel like I'm just on my own. People will be missing their skillshots at the start of the game, and they'll be missing their skillshots at the end of the game.
