Matchmaking splitting BTB group/squad

I like to play with my friends (who doesn’t, right?), but… every time we play BTB, they divide us into different squads.

Why? Seriously…

we search for a game in the same squad (4 players) and when the game starts, we all get randomly moved to other squads…

We are still in the same team (blue for example) but one ends up in the alpha squad, another in omega and two in delta.

Is this like a new feature or modern team balance tactic? or just a bug? Whats the point to play friends like this?

Just another example of 343’s own lack of social skills shining bright through this game.
