Ranked 5's Matchmaking

First off, I understand in ranked you play higher elo players, especially teams. However, my high bronze/low silver friends and I made a ranked team to have some fun. We only made bronze 5 but we are playing against teams with platinum and gold players almost every match! One team even basically admitted they play with unranked teammates so they can destroy lower elo players. I just hope someone at Riot see this and maybe just takes a look at the matchmaking in ranked 5's. I am sure some of you will just tell me to suck it up, but not all of us are planning to get to the LCS. We just wanted to have fun as a team, and none of us are.
