League of Legends RP Price Increase

League of Legends Competitive System Changes

Having a premade duo is a slight advantage, and while current Apex Tier (Masters, Grandmaster, and Challenger) players aren’t able to duo with anyone, the system only works off current rank. With this change, Riot are tightening up the Apex Tier restriction to apply to MMR as well.

The goal of this is to prevent climbing smurfs from being able to duo queue into Apex Tier. That said, decayed Apex Tier players and the highest skilled Diamond I players may also be impacted by this change.

Up until now, these players could duo and reliably get into Apex Tier games, which isn't fair when the people they're playing against can't duo. If this change works as expected, they'll evaluate shipping it to the rest of the world with plans to re-evaluate before Season Start.

Riot first rolled out this change back in patch 12.10 on the NA and KR servers as a trial and the results have been positive, so we’re rolling it out to the rest of the world. From now on, players with an MMR correlating to Master or above will no longer be able to duo queue in Ranked Solo/Duo, even if their rank is not Master or higher.
