Multiplayer definitely needs Equal Teams

I’ve been grinding the halo 5 beta lately and something that I have noticed are the extremely unbalanced lobbies. At first glance, it looks as if it is sorted by rank, which is a very bad thing. Rank is only determined by win/loss in this game, which is fair but unfair. If it is determined by your kda ratio, it would make a lot more since sense it is showing your basic skill more than the amount of wins/losses on your team. It is very unfair t the player to be matched up with a bunch if randoma with no thumbs and just get demolished, which causes you to get deranked.

With this said, if lobbies are balanced by kda, then a Win/Loss ranking system would make much more sense because it is balanced, and you can see who is the better team. Any thoughts?
