I totally agree with you. During one game alone I have had 10 accidental talks, on each side, where we let they other team know an important battle strategy, and vice versa. Also, its kinda scary to type because if you type it in wrong, like /s instead of /a (they're right next to each other on the keyboard) you could end up sending important info to the other team. I am filing a formal request to the dev team to fix this as soon as possible PLZ.
Anybody on this thread who supports me please write a similiar request to return the chat system back to the way it was. I miss the old system.
