When I make a new char, each char gets 22 letters from the start. Imade a new char today, and to my surprise, the moggle told me it mailed 2 letters back to sender. The letters had my Asuran gauntlets and onion helm inside. This 20 letter limit is something that could be an ever bigger issue, considering veteran rewards, and other prizes that get attached to your account. Still do not have my 2 items, and this kinda makes me sad.
