There used to be a stats page where you could look at the rank and % in all modes, and where you placed in different seasons. You could also look at your ribbons, social leaderboards and Horde leaderboards.
I believe you could also change the page to look at your stats from other Gears games as well.
Then TC rather lowkey just got rid of it, and the Gears 4 online store/inventory customisation. We got a solution for people wanting to create multiple skill cards at a time, then a year later it was gone.
