I'd almost entirely stopped playing Overwatch for a couple years, but I got back in recently and feel like the tone is overall better than it had been. I think a lot of the toxic players may have actually just moved on?
They also released player reporting and endorsements though it’s harder to say what the overall impact of those are.
Then it launched and I got bored after 1 month. Too few maps too few variety.
short of reducing the power of the ultimates: I'm not sure they can do too much about it
