Guild Wars Suggestions
Make it possible for Characters to get a Devourer as a charmable animal by bringing a devourer egg to Emryd the Tamer in the Zaishen Menagerie. (This idea was inspired by Joe,Devourer (The Rise of the White Mantle), and the Moss Spider Egg)
Have there be a special collector during special events that allows you to get previous Festival Hats of the appropriate kind (eg. Wintersday Hats at Wintersday, etc.) To keep it fair, make it so only hats the character is old enough to have been there for are available.
