My level 20 friend is paired against a Diamond player
He's only duo with one level 30, and he doesn't play ranked.
Honestly, that is fucking absurd. The enemy has a Plat and Diamond vs someone who is level 20 and still relatively new at the game.
EDIT: When I was loading in (I'm spectating since they started right before I got on) it said the Vel'Koz was Plat, but that was last season, him and their Pantheon are both Diamond V. Oh yeah, and my low level friend is the 22, didn't realize he ranked up a couple times. http://imgur.com/TrCiJzj
