Just had "Hero on the Halfshell" fail due to the tank not reading the chat log. It's sad because it's probably the only guildhest that will kick you because you killed something.
I cannot stress enough how important it is that all players pay attention to the chat while in a group or dungeon (This goes twice over if you're new to the duty). Not only do party members share tactics and important information through it, but boss queues and enemy spawn notifications regularly appear there.
Even if you're unable to type that efficiently due to console woes or some other issue, it's best that you show that you are aware of what is going on in the chat. This can be anything from using quick emotes, auto-translate, or simply following suggestions or orders made in the chat log.
