In today's update for Dota 2, Valve has introduced MAJOR changes to Ranked Matchmaking ever since the introduction of the gamemode.
Solo queue is back, and by that we mean true solo queue where all 10 players are NOT in a party.
Linked phone number, this means that all the players have to register a unique phone number to their account in order to play Ranked matchmaking.
There will be a two-week grace period from today during which players have time to register a number, but starting on May 4th, accounts without a registered number will no longer be eligible for Ranked play.
If a phone number is removed from an account after registration, a new number can be added, but there will be a three-month waiting period before the removed number can be registered on a new account. This is to prevent using the same number on multiple accounts. Online services that provide phone numbers are not allowed.
Party matchmaking has changed in a way that if a player’s Solo MMR is higher than their Party MMR, queuing in a party will result in the matchmaker assigning a higher MMR to that player. Effectively, these players will search for a match as if their MMR were halfway between the Solo and Party MMR values.
Matchmaking behavior has also been changed. First change is that if you enter LPQ (Low priority queue) you also get banned from Ranked matchmaking, in addition to your set amount of LPQ games. The ban will start at a low threshold of a few hours, and increase up to four days for players who are very frequently in low priority.
Second change is that much stricter punishments will be given out to people who ruin a game intentionally, while also improving detection of said players.
Valve has also issued a permanent ban to a huge amount of botting accounts, while also improving detection of those accounts.
And last but not least, ranked matchmaking will be unavailable for the time being in the following regions: India, Dubai, South Africa. As they say, this is mostly due to a huge amount of players using these servers for various Ranked Matchmaking abuses. As the unranked population grows in these servers, Valve will re-add Ranked Matchmaking to those regions.
I wish all of you a good amount of +25 in the coming months. And don't forget to register your phone number!
