This suggestion might be very niche, or maybe not, but I think it would be very useful and convenient if it were possible to alter the default keyboard settings in game to reflect the comfortable playstyle of the player. In the game, at the start of every character creation, the keyboard settings are defaulted to a specific keyboard layout. However, very few players actually use the initial settings that the game provides and upon making a character, whether it be for legion or the introduction of a new class or simply just wanting to start over, readjusting those settings can be one of the most annoying things to do. I propose that an easy solution would be to allow the player to override the game's provided default keyboard settings with his or her own desired layout, so that every new character that is created within that account can adapt that same setup for the player's convenience.
I think that it'd be a popular idea to have an event where face and hair can be transferred between same-sex characters for a limited time or to have a cash item that allows you to transfer a face and hair from one character salon inventory to another.
