Loot luck should apply if you finish an NPC in Mercymod instead of you having to put the NPC in Mercy-mode yourself as well as finishing the mob !

[Anabolic Man]

I think this mechanic is annoying, especially if your group pull several mobs. The group constantly have to check the hp of the Mobs and have to stop attacking right before the NPC go in mercy mode, so that the guy with the loot luck trinkets can put the mob into mercymode and then finish it. If you pull multiple NPC´s, you have to parry multiple mobs till your firend with the loot luck can put them in mercy one by one and finish them. This takes time and is annoying, becuase you have to parry multiple mobs for a much longer period of time, instead of putting them in mercy one by one for your fried to finsih them.

This need a change !
