So....
Rather than take appropriate action against spammers and cybermorons, WG saw fit to disable All chat in game. How very lazy and avoiding of the true issue. 90% of the entertainment value of this game is being able to hurl clever insults at the enemy team and be party to vigorous and energetic exchanges between teams. I realize there were poisonous individuals in the game that gave away their teammate's positions, but if WG would deal with those individuals in a swift and certain manner, we would still have inter-team chat.
Bad form, Wargaming.
