Hello,
I never really gave this much thought to have as a request, but after a recent experience, I am a little more keen on doing so.

Can we have a service were we can request names being horded by players be made available for use?

There is an endless number of characters you can go through on the Lodestone, that are level 1-5, who either started the game, and never came back...or created the character to hold the name so others couldn't take it.
Other games have offered this service, and they simply tell the player who is holding the name, to use the character, or lose the name.

There are many ways to do this, but at least something to allow names to be used by active players.
