Okay, I'm a legacy player and this wouldn't bother me at all.
Here's my honest perspective on the situation. Other people having the same stuff as me doesn't lessen the personal value of the items that I have. My memory isn't wiped, so I remember the experience I had getting those items. That's the things that's valuable to me, the memories. I can reminisce about playing 1.0. I even have old coil weapons and armors tucked away in my retainer inventories, and they're trivial to attain now, heck there are better dyeable versions of them, but I'll always remember the experience of obtaining them. Seeing other people with them doesn't bother me at all.
I guess I just don't really understand people getting attached to the actual items themselves, that's just bizarre to me.
