I'm about to go on a bit of a rant here sooo...
Today i was playing Halo 5 and our whole team was just waiting for one of the legendary bosses to spawn and just before we could kill it, some idiot from the enemy team shows up and steals the kill gaining 150 points for the enemy team. We then fought Warden Eternal and agiain, we had the spire but some idiot in his ghost ultra came up and shoot the warden in the back and "got" the kill, despite the fact our team did all the punishment THIS HAS HAPPENED TOO MANY TIMES!!!!

I propose a new system for bosses, instead of which ever team gets the final kill, i think the points the boss is worth should be tied to its health, that way say your team kills 30% of the bosse's health, then your team gets 30% of the points that boss is worth, or if the enemy team kills 40% of the bosses health, and your team kills the other 60%, then each team gets the amount of points they took away from the boss respectivley. This way to me is better becuase at least each team HAS to participate in order to get points from bosses and promotes teamwork and not individuality.
