Since I have been told that a) Zaela did the itemization for ED's and b) Zaela is back, I thought I would bump this post.
Basically, when I first got this item it had 3% stun resistance. About 3 weeks after having this item, the stun resistance disappeared. I got the item after the changes to ED loot went in, and after the stun resistanced was removed, I thought that the item possibly reverted back to the original stats(before the items were upgraded).
If you have time to look into this, Zaela, I would appreciate it very much!
Thanks a lot
