Suggested several time and always seems like a good idea. It essentially becomes a sort of "fitting fee" where you are paying dias to make an item previously fit to someone else fit to you.
Same for graduated ABL/fitting costs, to allow lowbie gear to be cheaper since they can't afford expensive stuff yet.
Alas, GF can't do it, only RW can. So, chances are slim and none, sorry to say. Would love to be proven wrong on this one.
This problem is much easier to fix, but would require work on DB.
Just change all gear bellow certain level (for example bellow L65) EoP. This way you have cheap binder able to unbind it. (500 PT or some small amount DIAS, I can't remember anymore what it was)
It is single field in item table that tells game if item is EoP, B or NB.
Yes, we discuss this many times, this would mean that instead of selling ABL they would get more DIAS by higher volume of binder, but of course, they will never do it... there are still 1-2 players left that will pay ABL for L55 gear most likely...
