Custom crucible matches! I have such extremely fond memories playing customs with my clan every friday night back during the Halo days, and some of the best game types came from customs! Adding customs will bring more people, especially those in clans, together for some game time, and training, as well as opening the way for some MLG and other competitions, which will shed a better spotlight on Destiny's PVP elements. Not only will it test the skill of gaurdians further in the crucible, but it could bring about some new great games, I'm sure everyone remembers Duck-hunt and mongoose racing! Not to mention the jumping challenges. Even Griffball came from rooster teeth getting into customs! Customs in Halo gave me some of the best memories I've ever had with those games, and helped me build lifelong friendships with many of my clanmates and others. I also miss game types like capture the flag, which I think would be a great gametype to add to the Crucible. Let me be clear. I don't want Destiny to be Halo, but I know that Destiny can be more than it is! Destiny is a great game and I love it already, but Customs crucibe and being able to play with more of your friends or clanmates, I don't know a soul who wouldn't jump on the opportunity!
