I have many issues with crucible, but the majority of the problems I have can't be fixed so I won't bother mentioning them. There is one issue however that can be addressed by Bungie. One current frustration I have with Crucible is when playing by myself in any playlist, I often get matched up against groups of players on the same fireteam (meaning they went into matchmaking together). It's not always a full team of 6, or a full team of 3 for Skirmish, but it's usually enough to make a difference against a total team of randoms. It can be very frustrating to face a team of people who are in the same fireteam together since being able to coordinate strategy is often more then enough to beat a team of random players even if said fireteam isn't that skilled.
What I'm thinking is that if you go into Crucible with a team, then the priority should be to match you against other fireteams of at least the same size. If you're going into crucible by yourself then the system should prioritize matching you against other solo players. I realize it's not perfect since other fireteams might not be found to fight against for various reasons, and slots against and with other fireteams that don't have a full compliment of people would necessitate solo players or smaller fireteams being used to fill those slots, but it's a step in the right direction and would personally alleviate one of my many frustrations with Crucible.
I'm curious to see if others share my opinion about this matter and if you all think it's a good idea.
