I love playing valorant but there is 1 problem that i keep facing. I feel like comp is kinda rigged, I played it and got match mvp but only added 12 RR while my other team people added like 20 ish and they are higher rank than me. Then next comp, we lost and I reduced 27 RR, I wasn't top fragging but still, how? This is kinda messed up and I hope there is like an explanation to this.
