tripels in ranked?

I am someone who really likes to play with my friends, and recently we have decided to play nothing but ranked s we can get better and progress together. But the problem with that is we can't always play together. Sometimes we want to play in a party of 3 or even 4 people, but ranked only allows for duos. I would play in a 5v5 team but I don't have enough people to do that. It's kind of upsetting because we all want a 5v5 team but don't have people for it. On the same token we want to all play ranked (being the 3 of us) but can't and constently need to rotate because we can only play duo games.

Do you think we can play with more then one person? I understand the full party thing because if you have 5 people just make a team. But I am only asking to raise the number up by 1.

Anyone else agree?
