Gravebind gloves + IIQ/IIR gear not working (properly)

I recently got the Gravebind gloves (the ones with:nearby enemies killed by anyone count as being killed by you) and i'm trying them while playing MF in a party with someone. Got 60 IIQ and 170 IIR with everything up. IIQ seems to work since we're getting a lot of magic/rare (way more than with other builds) but there are few uniques dropping, almost as IIR isn't working. Was running 110% + quant maps.

I'm curious if this is intended or just a bug. If it's intended delete the thread pls to not mislead other players.

Update


Wiki says : "When in a party, only the statistics from the player who lands the killing blow on an enemy is applied - multiple characters attacking a monster will not stack their item rarity bonuses together."


But gravebind gloves have the line: " Nearby enemies killed by anyone count as being killed by you INSTEAD ".

That means there is something wrong with the way it works. My IIR is not applied instead of the other party member's IIR even if i'm the one killing the monster because of the gloves.

So it has a bug right now?
I want to use the glove on animate guardian with Item rarity support too.
But it seems that doesn't work. :(
