no ranking - If you ever end up against someone decently close to your skill level odds are your teamates will have never played halo in their lives and you can enjoy being spawn killed for an entire match
playlist options - if you don't like objectives you're screwed
infinity slayer - the most skill diverse playlist completely unfair either you dominate or you end up with people being dominated
big team slayer - holy vehicles theres not a single map that isn't completely dominated by vehicles whether it's the scorpian the banshee or the wraith there's no real gun play it's just a cluster**** of vehicles
regicide - can we say luck based? i was king yesterday about to win my game was 100 points up and had max bonus, someone gets a lucky ordinance and spawn kills me with an incinerator cannon until he wins with 2/3 the kills i had awesome
