I can confirm that at the end of Alderaan warzone, an Imperal said "Too easy". Im on the republic side. I didnt understand why the player said it was too easy if we lost and it was a good match. The only way that statement made sense was if the player was on the Imp side.
I did a /who on my republic toon and no results appeared. I switched to my Imperial alt, did a /who and there he was.
I dont know if this is how general chat is supposed to work, or if the Imperial was doing something he shouldnt, but I do know it happened just as I said. The imperial toon said something in general chat and my republic toon was able to read it.
