In the next Matchmaking update you guys should remove custom load-outs from Big Team. This would eliminate the problem we have with players spawning with plasma pistols/plasma grenade combo, which is killing vehicle game-play. Replace this with game-types that are: BR Starts, DMR Starts, or AR Starts.
This would allow more "Halo like" vehicle game-play. Of course you would have to add weapons on the map that spawn in set locations at set times. Gee, that is such a good idea, I don't know why it was never in Halo, oh wait, it was in every Halo except this one.
Also this would improve player's map movement on Big Team games, because it would encourage the use of something other than the DMR, thus players would not be DMRed to death constantly upon re-spawn. In fact, these changes would cause the use of weapons to be more versatile, making this not the "one gun game" that it currently is.
Encouraging more variety makes the game more interesting, more fun and less boring. This is the most boring Halo ever. Run around with the DMR, shoot, die, re-spawn instantly, repeat. It gets old fast folks. Come to think of it, maybe these changes should be implemented in all game types, and the whole Infinity game-type, with the personal ordinance and such, and personal load-outs should be scrapped.
