Arenas ranking system doesn't exist?

I'm now in Gold 1 ranked arenas, and I am definitely noticing that the ranking system doesn't seem to exist? My team-mates and enemies ranks are all over the place. I will be gold 1 placed with someone in bronze or silver and the other team will be all gold or platinum (as an example). It makes the game very frustrating knowing you're at a disadvantage or that you are going to slaughter the other team.

Fix the rank system?
