I'm not sure if this has been fixed in today's patch, but yesterday (post-launch) Zandalor's Trunk's comments were not voiced (if they're supposed to), nor are the statements being recorded to the chat-log window. They only appear (very) briefly over the wearer's head, and are easily missed due to other conversations happening at the time and/or because the color of the text blends in with the background.

I suspect there isn't supposed to be any voice audio associated with the trunks (disappointing, but understandable), but the comments the trunks are making should be logged to the chat window for reference like everything else that is spoken. As it stands, I have missed almost every reference the trunks have made up to this point.
