Ha;f the questions at the live letters are usually a waste. They are questions that are usually already answered and people can't be bothered looking on the lodestone for or something so obvious from the direction of the game, it answers itself.

Although I reckon some of those questions are hand picked for that reason, to make it seem like they are answering community questions without having to put much effort into thinking of answers when they answered them months ago because yes, this question was answered when the system came out. That's how lazy some people are when it comes to finding the answers themselves.
