Bungie should add an infected mode to Crucible. You can make it always night and give a debuff like weight of darkness to everyone but one person who is infected and has the appearance of taken (or some type of glow to show they are infected). That infected person only has a hive sword (like from Oryx/crota) as a weapon with no other main weapon, no supers either, (maybe keep grenades or give an acolytes eye), and no debuff as they have the sword. When an infected kills someone that person respawns immediately as infected and gets a sword which takes away the debuff. When the infected die they have a respawn delay, and come back still infected with the sword. Game ends in a specific time period or whenever everyone is infected. It is similar to the Halo infected mode, and could be just be called taken (like the guardians are being taken this time). I like this mode from time to time as it is more relaxing then constantly trying to get points for a match. Breaks up the bore of constantly worrying about K/D ratio in regular multi-player.
