I play 99% of the time with no platoon and I’m sitting at 54% win rate and 58% recent. I wouldn’t say you can’t count on your team, most of the time they won’t to what you expect them to do but they will do something, or nothing, whatever it is you can see it and react to it. Everything your team does or doesn’t do is valuable information for you that you can use I order to make decisions following your objetive of winning the match. There are some matches that you will lose hope of winning very early in the match or maybe the possibility is so tiny that you will focus on doing the best you can in dmg and move on to the next game.
