I have some confusion with the ranking system, I don't understand why when playing a new map that I have never played before and then getting an S rank FC with no 50's just a few 100's causes to me lose ranks. I could understand if it was a map that I had already played before and I got a worse accuracy or etc but it wasn't :/ Seems silly that I can just lose ranks for causally playing a new map as a warm up that I didn't even do that badly on. Please can someone help me with my confusion here XD
