in pvp i see people with the bubble chat sign, but they're really text chat. i don't mind, but sometimes it makes me feel like an idiot when i say all this random stuff to myself (because i'm bore) and it turns out they heard the whole thing ya so, just so you know
Under Options is the ability to hide your opponent's Chat in Player vs Player combat. If you have this option enabled, during a PvP duel: Anything you type cannot be seen by your opponents, but can be seen by your teammates and spectators. Anything your opponents type you can’t see, but can be seen by their teammates and spectators. All Menu Chat can be seen by everyone. You can change this setting at any time, including during a PvP duel, but it will not take affect until the next turn.
