It did, though. I haven’t been in gold for years. I was diamond before the rank reset in season 12, then barely played support after my placements from that reset (which put me in plat 3). I made it back to plat 1 this season when I played support. Now I’m in plat 4.
It’s why I’m trying to get a better understanding of how it all works. Here are my seasons since the reset in s12 https://i.imgur.com/zjdHyFN.png
