Blizzard's hero-shooter Overwatch is already poaching players away from Valve's ridiculously popular Team Fortress 2, months before its release.
Froyotech, one of the most successful Team Fortress 2 teams around, recently blamed a rare loss on Overwatch, claiming the game had been distracting the team.
"Many of our teammates, since the release of Overwatch, have had waning interest in TF2 (myself included). As a result, our team cohesion took a heavy hit," said Froyotech team member Clockwork.
Additionally, Tempo Storm — an organisation possessing pro teams in Hearthstone and Heroes of the Storm - has been actively recruiting North American Team Fortress 2 teams for the upcoming shooter.
Blizzard does not use "eSports" when describing Overwatch, but the studio is banking hard on the game, while its design suggests competitive play is virtually a given.
The free-to-play Team Fortress 2, on the other hand, has been lagging behind in the competitive realm, with competitive matchmaking being a long-requested feature.
Hints were found of competitive matchmaking in the recent "Gun Mettle" update to TF2, but as of yet, it has not launched.
The two games bear a number of similarities, primarily in their cartoony art style and team-based capture gameplay, but Overwatch's hero roster promises deeper gameplay options.
Overwatch will launch in autumn 2016 on new-gen consoles and PC.
