I'm not getting key fragments

I used to get fragments all the time, I have 2 right now and haven't gotten 1 more for a couple months. People have said "you have to get honored" I get honored almost every game so I don't think thats it, do you have to have a good score? do you have to be non-toxic? Like I just don't understand. I even used to get them when I logged in it says something like "You have ben given a key fragment for getting 30% more gg honors than others" or whatever [sg-janna]
