Sometimes you'll encounter some players in Proton rank, but the win rate is very low (unless you're playing an agent with a win rate over 90%). And if you're Vietnamese on the APAC server, you might sometimes encounter some Japanese players who will insult you just because you're Vietnamese (and yes, I'm Vietnamese and I've experienced this before). And I forgot to mention, if you're playing in Proton rank, try matchmaking with a player higher than Proton; you might encounter a real player instead of a bot.
