I am suspecting that Overwatch is overtaken by a bunch of cheaters. Now what?

TBH, Gears 5 is too intensely stressful. I think I will do Just Dance 2020, Final Fantasy XV and Kingdom Hearts III for the time being.

It's not just that, but I got so angry at other players that I couldn't control myself and I have been hit with Communication Bans from the past and this whole thing is to be blamed on Overwatch Comp mode. I wouldn't be getting these past com bans otherwise.
All I know is that if my account was to be banned, then my gaming days would be over.

Competitive Play in Overwatch has always been blamed for affecting my account. When I got the communication ban, I was also kicked out of the Xbox Ambassadors Program, too. 2 months ago.

if your experiencing problems with the game players causing temper i suggest playing a different game till the second one comes out so you dont have to deal with cheaters

I understand your frustration.

My son has the same in-game issues, however, as mentioned before not in full control by Microsoft so you need to report to Blizzard so they can take steps.

In the meantime I recommend Gears of War 5! It's a cracking game! May be worth taking a break from the game frustrating you at the moment - that solved my sons issue. He had a break for a couple of weeks, went back to it and was fine then.

unfortunately, Microsoft can't do much since the servers are run by blizzard. Make sure to block and report cheaters and maybe contact the developers to see if they can do something about it.
