[2022] I‘m freaking Master… Why do I even bother ranking up.

Are you in a party? And this is Ranked?

OK, I'd need more info to pull the exact match, but a Master partied with Diamonds will be considered a Diamond party.

Emerald players can match +1 (Diamond) and -1 (Plat). So if you match with an Emerald, you can also see Plats.

In addition, if you are in a duo, you can see Golds if this happens:

• high Gold duo with a high Plat will be considered a Plat team
• Emerald soloQ player can match Plat (-1) and Diamond (+1)

So you have a Gold on your team, but they are partied with a high Plat, and that party is, on average Plat.
