What’s the best way to play theFINALS solo?

Guys I love theFINALS. I’m a season 1 OG. I own every gadget and gun in the game, but the single player experience is really awful. I’ve reached at least level 100 every season since season 2 and I’m a level 74 over all so I know what I’m talking about. WT and tournaments are terrible. I’ve only got like 3 tournament wins in all the time I’ve played this game. Why are the players on my team always so bad??? I mean it’s consistently me with like 10 kills and 3-4 revives with 1000+support score and we lose everytime. I play all the classes regularly, but like to main medium. I’ve tried everything. Is there a better way to play solo, a secret trick I don’t know yet, or should I just quit playing ranked?

(My friends do not play the game, and they don’t want to so I’m forced to play solo)
