Halo ranking system question

I have a question about the ranking system. I really really have to admit I LOVE LOVE LOVE what they are doing with the ranking system really smart move on their part. But my question since the ranking system is identical to League of Legends and StarCraft. Will I be able to duo for example say I am Diamond and my friend is silver. Will we still be able to go into matchmaking queue. Because in League Of Legends and StarCraft you are not allowed to duo with anyone who is two divisions lower than you. Thanks! So excited!!

I believe it would average based off of both of your ranks and find the closest parameters to match others in similar ranks.

Just gotta wait and see.
