Ok, so I tried to make this thread when this feature was announced and it got closed.
Now it's been a couple days, 8 pages later in the other thread about NPC sharing and the topic I want to discuss hasn't been addressed.
Rather than derail the other thread I am making this one and hopefully mods will see that the topic is different from the other thread.
So according to the post on Rare spawn sharing, it works with the enemy faction. This in itself is not a big deal, what is bothering me is that enemy players can still get credit after dropping combat. Imagine this scenario: You are fighting a rare spawn on a pvp server, an enemy flies down and 'tags' your spawn, you instantly turn your attention to the enemy player and kill him. Then you kill the rare spawn, you get loot and if I am understanding this correctly, so does that player that you just killed.
This doesn't sit right with me. I'm fine with my own faction getting credit but why should the enemy get credit even if I kill him?
