So I've been having the feeling that messages send over party/guild/alliance chat where not always fully received when CC'ing, as conversations didn't always make any sense when hunting for bosses. I've tested and confirmed this using two chars in the same guild, one CC'ing and one idle, and someone spamming messages in the guild. Here's the results: Alliance chat on the CC'ing char: Alliance chat on idle char: I'm not sure if this a client issue, but it certainly is quite annoying when having conversations while hunting for bosses.
