Won 12 Doubles in a row and my buddy has went up 2 ranks and i have stayed the same rank. Just wondering whats going on.
It’s intentional; it is the new way ranks are handled in Halo 5. Your CSR (rank) will not go up if it is higher than your MMR (true skill). Your MMR is hidden so you don’t know what it is, but if you are only gaining +1 CSR for a win and losing -15 CSR for a loss, it means your CSR is too high and the game isn’t letting it get farther away from your actual skill level.
