Maybe I wasn't clear with what I said. Most of the other players that were in top spots are dropping due to the strong decay. I wasn't really fighting that many strong players recently and ended up above a lot of people I shouldn't be at this point in time, based on the people I was dueling for the past few days. My stf that was previously on the rankings with ~350 points, I went on yesterday and only had like 120.
On my main, I got a few points by fighting people and getting ~2-5 points per win, nothing special. I wasn't fighting Saul or Marcus, etc. or anything like that, and many of them dropped hard.
