Ah what you are asking is if you pick the lawmaker for martial artist if you could switch it over to your lance master later.
Well that has not been answered yet. That is right.
As far as they have told it first binds when you open the chest.
Question is if they create the lawmaker model for later classes too. I highly doubt it that they think of that.
Are the Lawmaker avatars a profession-related avatar, or a class-related avatar?
In Lost Ark, some avatars are bound to all warriors, or all mages for exemple. I tought it will be the case for the Lawmaker (at least you can give it to other classes of the same profession).
Yes - Gold Founder Pack Avatar / Lawmaker will be a Class bound . Meaning if you Open it on a Berserker you will be able to wear it on Gunlancer or Paladin aswell - tehnically you could on destroyer too when the class is launched , unless they forbid it )
