Can someone please explain how Arena ranked match making works cause I just did arena for the first time been waiting to get ninja's to do it and my first fight EVER was a Angel Konan, Shakr Kisame and Edo Hiruzen.

Im level 90 with 55k power (I didnt care to level freeze) and was first time Training school ranked in arena so how did I get a super pay to win team as my first fight.
