Despite being in a full clan, roughly 90% of my matches are solo. If you want to do "well" consistently you either need to ignore your stats and go for the win or ignore objectives and go for stats. If you want both you either need to git gud or only play with a fireteam. 0 communication with a bunch of randoms, most of whom are horrible at this game, means in the long run you'll end up with around 50% wins. You'll have streaks of winning and losing, but do enough and it'll even out. Of all the issues with this crappy game, solo crucible isn't one of them.
