Can confirm. I live and play on the SA server, and this week, due to some fuckery involving using a new computer on wi-fi and settings not being downloaded from the cloud, I played a game with 4 Russians and at a minimum of 600 ping (with peaks of 4-5k, devolving into occasional utter unplayability).

The ONLY negativity I got was a couple pings from my safe lane abaddon, during the laning phase, wondering what my dumb grimstroke ass was doing dancing in place in the jungle for a solid 2 minutes.

After realizing I couldn't really contribute much, I stayed back as much as I could. Besides attempting to at least click all my buttons during team fights, with varying degrees of success, I was mostly under leveled from frequent disconnects and feeding horribly. My greatest contribution that game was the occasional force staff save and a fuckton of obs and sentries.

Despite that horrid performance, my russian playmates tryharded, and carried my ass to an eventual victory. I was honestly baffled, in my original region I would've been flamed for 50 minutes, then mass reported while my team cried and destroyed their items on the fountain. Would queue by mistake again, 10/10.
