If this was a default function (there is a mod already that can do this!) it would force people to actually write in a more or less civilized way. Otherwise nobody will hear them anyway.
Since I use this mod I actually look on the chat because there are people who are capable to write useful stuff on the chat.

If you talking about “Миииш? Левооон? ;-)” thing, SerB called moderators to ban this guy

Funny though why on earth haven’t they done anything about the British line. The Cent mk1 ammo is way too expensive , isn’t it enough that hey handicapped its armor. The fv42 needs a gun turret armor or speed buff , and the fv heavy tank well no comment , that thing was made up by wg because they couldn’t be bothered to finish the tree. They even admit to it. Lousy company.

Frankly, with usually half the players on my team not speaking English anyways, the chat is moot. If you want to communicate, get a headset and a teamspeak server and set up your teams. random battle is just that, random fighting without tactics.
