This has been an issue since I started playing on Stake over 3 years ago. Sometimes you can run autobet for awhile without stopping, but most of the time it stops every few minutes. It has something to do with how cheap their servers are. I gave up on playing Originals all together because of how unbearable it is.
I'm a GM support and diamond DPS/tank. I haven't played comp in a few weeks though. But for sure, Overwatch community is one of the worst I've seen online. Almost every game, you'll find people yelling/insulting/crying. And not just kids too lol, grown ups act like children all the time.
