FFA Ranks are broken

I beat a whole game of onyxs yet only gain 1 CSR, Or ill beat champ 1 but because 2 ppl in the game were diamond Ill gain only 1 CSR
Ranks in FFA are broken, if i can’t gain more than 1CSR after beating them, THEN DON’T MAKE THEM MATCH ME IN THE 1ST PLACE

It’s intentional. It’s the new way that CSR works. It’s all explained here.
