You could have something like a quest pop up in your quest window:
My Second Birthday!
"Congratulations! You turned two years old today and your good friend [who-ever] the Weaponsmith has granted you with a special honour!"
You open your gift box to reveal a
Weapon Ticket.
You take this ticket over to [who-ever] the Weaponsmith and he gives you a selection of weapon types, all green and all inscribable and clean (so you will have to upgrade them yourself as well) and all beginning with your name, so I'd pick (for example) "Elisa Sarendil's [...]", in the [...] box you'd be able to fill in a second part to the sword's name, for example, "Rake". My sword's name would then be "Elisa Sarendil's Rake". These weapons should be tradeable, because the name already links them to your character. And who wouldn't want to have someone call out their weapon in a mission and it actually has your name on?
If that is too far-fetched, give us a special armour that has our own name on it. Customize it per account, please, so other account characters can use it as well.
If that isn't possible, either, the disguises sound a lot of fun! Of course, any special item that we can use indefinitely and is humurous or "cool" would be welcome. I think we should get a minipet
in addition to getting one of these new things, but I'm just greedy like that.
