The win rates for Deadlock heroes have been revealed, and in the last 11 days, one character has been played over 2.5 million times

It's not been long since Deadlock officially launched into closed beta, but even still, some players are starting to figure out which heroes they really click with and which are simply too overpowered to ignore. 

Thanks to the site Tracklock, we can see not only who the most popular hero picks are but also how successful those characters are in terms of win rates, pick rates, total games, and total wins. Most of the heroes up towards the top (and bottom) are pretty expected. Seven, who seems to be the most popular hero, is currently sitting at the top with a 57% win rate out of 2,518,656 games and an impressive pick rate of 92%—he's in almost every single game I play. 

Seven is a pretty lethal hero and also very easy to master. His Lightning Ball is a great way to gather a bunch of souls in one go, and it is also a really annoying ability to play against, as it can deal with 70 damage, slow 40% movement, and zone enemies really easily. The Storm Cloud ultimate is also a lethal ability to have in this game, considering its reach and duration. Seven has even already been nerfed in a recent Deadlock patch, but it's honestly not that noticeable. 

Although I fully admit that I am part of the problem as Seven is also my most played hero. Out of 25 games, I've won 20 of them, a statistic that I was kind of proud of until I found out that everyone else and their mum also shares in this success. 

Other heroes in the top five also include Warden, McGinnis, Haze, and Lady Geist, although only Haze comes close to matching the total games played as Seven, with 2,434,513 total games so far. 

On the other hand, the worst five characters are currently Yamato, Viscous, Grey Talon, Paradox, and Vindicta. Although to be fair, Yamato and Viscous aren't beginner-friendly heroes, they can be good after some practice. I've seen Yamato tear apart teams with the right kind of build and sequence of abilities. Characters like Grey Talon and Paradox often need to rely on having a solid team
