I tried searching but can't find the reason why the site made a change. The leaderboards were and should be based off of when the trophy was earned (based on the time stamp). I notice now that everyone that shares a common point level gets sorted by the PSN Id. So... why was that changed?
I don't like it all. My PSN Id starts with the last letter and I will always be at the "back of the line". This is like the "index rating" that credit cards use - I get to know my leaderboard ranking based on my "group" at the current trophy count. I am losing interest in this site becasue of this. If I can't see the progress of my achievements on the leaderboard as earned (and not like in line for school pictures), there isn't much here to keep me coming back to the site. (I also never like that someone with zero plats and 1,000 bronze trophies would be sorted above me based only on total trophy count.)
Other than that, I overall enjoy the site.
