That winrate is insane, I don't know how you do it! Even my friends with 6+ KDRs or top 500 pred on PS4 don't have winrates even close to that.
You should post up some gameplay sometime, if you get chance. I haven't seen any of your full matches in a while (I think the last one I watched was a 20 bomb in S3 or something?).
On the topic, I almost hit a 20 yesterday. 17 kills and the last team is lifeline, bloodhound, octane. I down blood and octane then lifeline appears and revives both in quick succession. I was the only one left alive on my team and I just couldn't deal with it. Suddenly I was in a room with 3 players up with more than 400 total hp. I died.
Didn't really matter though since it was on Octane anyway and I have a 20k badge on him. I've managed to get 6 of them with him so far, and most of them are on kings canyon.
Also just wondering but what servers do you play on? Because I'm surprised I've never seen you. I see the top EU players all the time. Had a series of games with Cheekyclassic last week for instance (top crypto). He doesn't win often though, since I think he solo queues. Usually seemed to end up dead before I found him.
There's not that much to it, in S7 I just mostly played with really good players, some of them a lot better then me. I'm on different servers depending on weather I'm playing with EU or NA people. I also use anonymous mode with no plans of turning it off after some random streamer lost his shit after I killed him, screaming how I'm not famous and shouldn't use it. :') Like I said, I kinda suck now and not doing nearly as good this season.
Top 500 Preds obviously won't have a high win rate because they focus on ranked where winning is 10 times as hard... Cheeky almost exclusively solo queues so his stats don't reflect how good he really is. Doesn't win a lot or care for it, just goes for kills. He surpassed the previous #1 Crypto for kills recently, heh. Played with him in S7 once and asked if he gets any days off the game with that many kills. The answer was no, I believe, grinds on stream and off.
Some Xbox facebook streamer hit 3000 S7 wins with Bloodhound with a 60%+ win rate. And for actually ridiculous stats check out golden boy on yt. Averaged 2400 damage and 10 kills per game in S7, stats wise he's in a league of his own. Seems like a shitty person, though.
