We made some statistics using blizzard’s api about heroes usage and winrates in Overwatch competitive play of Season 3. The special thing is that we used data only from top 500 players, so on this page you can observe most skilled players’ preferences. You can see stats about season 2 here. Charts are being updated — come again to see fresh stats.
The first graph shows a top mained hero. A lot of players indeed prefer playing one peculiar hero much more often than others. Often they play this hero more than 50% of all games.
The second graph shows three top mained heroes.
The third graph shows total amount of games played by each hero.
The fourth graph shows heroes’ winrates.
A lot has changed since the November’s patch. Soldier: 76 remarkably surpassed McCree and now is leading in the offensive role. Zarya lost a lot of her popularity and now is only the third most picked tank. Also we see less expressed prevalence of some heroes, what says (probably) that patches are doing their job to balance the game.
