Seriously I am now sick to death of my team mates Quiting and going round Spartan charging to get each other killed. I can’t escape the ranks of silver 4- silver 6 (max) it’s based on winning but how can you win if you get stuck with absolute YOINK! Yet when I check what ranks they are there in gold to platinum. Just YOINK!
Just keep playing and you’ll rank up if you’re good enough. I play solo a lot, and also have games where people quit. But I manage to push to Diamond every single month, although I needed a team to get to Onyx. No offence, but if you’re stuck in Silver, then you’re not going to make it much past Gold at best.
It’s been said time and time again here - get a fireteam. If you play with 4 people regularly, you know they’re not going to quit. There’s a recruitment section on the forum, and various other sites to find teammates.
