The official Dota 2 Twitter has just revealed the dates for the next Dota 2 Ranked Season. The new season will reportedly arrive in January 2019. The ranked seasons in Dota 2 are a chance for players to recalibrate their medals and possibly improve their standing.
The next ranked matchmaking season will begin in January, so anyone on the verge of their next Rank Medal still has a few more weeks to level up their game.— DOTA 2 (@DOTA2) December 19, 2018
The current Season 2 of Dota 2 ranked started on the 6th June 2018. The different ranks in Dota 2 depend on your MMR. Each win allows a +25 MMR while a loss means a -25 MMR for players. While there are no fixed tiers for the next rank, the approximate levels are based on your performance over the season.
Last season, when the ranked seasons were renewed, a new rank: Immortal was introduced. It’ll be interesting to see if the new ranked season brings in more changes to the model.
