I think it would be fair to say that when the Predator is killed, the XP should be distributed depending on the amount of damage each player dealt to it.
I’ve had my predator kills stolen a number of times. I’d use the Yautja Damage perk to deal the majority of the damage and having another team member swipe the kill last second and be rewarded handsomely at the end of the game for having the last shot.
Is this just me?
