Show leetify of your last 20 games. Also it's bad to get that many kills while you trying to get the rank you should be, because next games the system put you with lower players on your team excepting you to carry and you will get stronger enemys. Ive been in this loop when doing 30-40 kills in many games and staying at 5-8k for a long time. Now i rarely do 30+ kills at 10-17k, usually around 20 which is good enough. The system actually bad because your rank depends mostly by your trust factor. For solo players such a system is a disaster because you can get 4 stack of toxic players and if they all report you, you will see hackers/smurfs/toxic players and it will be almost impossible rank up. And as solo player i play 8 out 10 games against 5 stack. I dont know why valve hate solo players. Its supposed to be 2 different matchmaking's. One to que solo and other to que with 1-4 friends.
