So recently, I linked an article which addressed the issues many players were facing during the Beta Stage of Overwatch. Luckily, many have been able to fix it with Kill Ping as it reduces the lag and ping problems of the game which more commonly happens due to lack of servers and inappropriate data routes.
I follow their website regularly as it gives some insights to the games I play and more recently Overwatch has been added to the list as well. As part of Overwatch's recent launch Kill Ping is offering free subscriptions so that more and more players can try and play it with reduced lag/ ping. So if anyone is having problems playing the game or any other major MMO then feel free to TRY IT.
Let me know if it was helpful.
