@ popps Answer, drop them on the ground if you find them so offensive.
Problem solved. We do not keep every item in a corpse.
I am sorry, but, as I tried to explain, it takes anywhere from 40 minutes to 1 and a half hours to kill all that stuff and, at least to my opinion, dropping on the ground or, in the trash bin, the product of that chunk of a lifetime of a human being, I would find it unacceptable.
It would be a whole lot better if, instead, these items where to be given some tangible, practical use that would justify the time spent to obtain them.
Their Deco function can be acceptable for 1, perhaps 2 of them but more?
What on earth would a player want to do with 5 or perhaps 10 equal ones of each of those 7 Yukio's "Deco" items?
Personally, I think that, whenever the Developers Design content like this, they should keep in mind these issues and always give a "secondary" usefullness to whatever Deco item that they introduce in the game so as to avoid players to have to face the dilemma of either having to stock them up all for nothing, just to take up their storage space, already quite stressed out, for good number of players, OR, have to throw them away thus, basically, throwing the time invested in getting them, all for nothing.
Time is what matters most as once gone, it never comes back.
That is at least how I see it.
