I've been gone for about 6 months and been back for about 6+ weeks.
Bring back chat. I'm sure its been said before.
Make a big announcement about people calming down on "cancer" comments, or whatever was getting too carried away, and that WoT will restore it for the time being?
In 2 1/2 years of playing WoT, there were only a few times when taunts were over the line. The rest was just "Trump talk".
And being able to taunt and talk with the other side livened up the whole thing.
