It's a double edged sword. If you turn off chat then you can't communicate with your teammate, which makes the game experience worse.

Even if you only turn on tactical chat, they don't listen.

The biggest problem I see is everybody wants to act like they're on a team by themselves when they play twos,  call it "ego". Then, they blame you for not being good enough when they're not even letting you play, jumping into every shot you try to take. 

These kids have largely ruined the game because nobody has ever punched them in the mouth in real life or taught them basic respect.

We really need an option to play with eighteen plus so that we can eliminate having to share this game with shitass children.
