Definitely wouldn’t be surprised - MS have been making noises about reducing the level of access non-core Windows services get after the cloudstrike fiasco, and given MS’s patch stability lately, I would also not be surprised if something leaked out early.
Good news for those that enjoy the mode. Personally as a tank main who moonlights as support, 6v6 was not for me (even though I had OW since launch in 2016).
Playing just brought back the trauma of OW1 one-trick roadhog tank duos and healbotting, and going back to 5v5 felt good to me, even with all the counterwatching.
