What Are The Overwatch 2 Ranks?
The Overwatch 2 ranks are: Bronze, Silver, Gold, Platinum, Diamond, Masters, Grandmaster, Top 500 (lowest to highest). Each rank has 5 tiers with 1 being the highest and 5 the lowest as shown in the picture below.
How Is SR Determined?
SR or Skill Rating is what determines your rank. Each role has separate SR and you receive a rank once you have finished your placement games which is 5 for each role. Once completed your placements your rank will get adjusted every 5 wins or 15 losses. People have complained about the system so try not to be discouraged when you go down 2 tiers at once even though you finished with a positive set.
Rank Rewards
You do get rewarded for all your hardwork aside from a shiny new rankup you receive purple points that you gain from every win. These can let you buy golden guns for each of the heroes. Now you have a shiny new rank with a shiny new gun for your favourite hero! Overwatch devs have spoken about adding new gun types to the game but it has not been confirmed yet.
