It seems like the only agent you are great at in ranked is iso, likely meaning that you overheat quite a bit, which is fine on Iso, but on people like Omen, its not great. I also am pretty sure this is the case based on how many deaths you average per game. Your aim is good, but your teammates may not be, so getting yours and playing numbers (to win the round) might be better than pushing for a second and thinking that only you can win every round by killing 5. This should help you at least up your round win percentages, but may not be as flashy. However, there is no way for me to actually know this without seeing how you actually play, but its probably either overheat, or baiting teammates.
