So i join this group of breakout players with mics who had just done their first ranking match, So i play ten matches with them and i see how they got platinum and gold for their CSR.
So i finish my last game, and what do i get… Bronze 4.
This has pissed me off, I have added my game history from these games below
I am pissed to no end.
