Rank/Tier system is beyond broken

This player in my current lobby has a Kill-Death-Assist spread of 112-123-47 (-.6 k/d/a ratio) and in 10 games is 7-3 with 198 medals and is Onyx

I am 161-59-71 (11.9 k/d/a ratio) and 8-2 in 10 games with 314 medals and I am Gold 2.

That, my friends, is more broken than MCC.
