Killing in the name of... - who gets the kills counted when hunting with a team?

Question

The quests listed under Killing in the name of... category ask you to kill a given number of creatures. This is easy to understand when hunting solo, but what happens if you hunt with a team? There are no partial kills, so who exactly gets the kill counted if several players contributed to killing the monster? Only the one that dealt most of the damage? All of them? Noone?

Answer 1

Since the winter update 2017 all players that have dealt damage to a creature will get the kill counter in respective tasks as long as they're in a party with the highest damage-dealer and shared experience is enabled.

What if shared experience is disabled? Will only the highest damage dealer get the kill?
