As we all know, we gain points from sparring that will give us a rank in the leaderboard. Also, we get another rank if we change from idev to pc/android or the opposite way. Basically, sparring using both idev and pc will get you two ranks in the leaderboard, or even three ranks if you use android, IOS and web. "Mia" is an example, as you can see she is currently holding #33 and #34 in this season. As we also know, we get another rank/place on the leaderboard if we sparred from more than one different location. "Droon" is an example, he is currently holding #2 and #40 in this season.
I believe this had to happen because of the sparring filter? Isn't there any other way to keep the sparring filter without having to create another rank if the player changed his/her device or the location they spared from?
Because in my opinion, I think it's unfair to those players not being able to get one high rank. If this thing didn't exist, Droon would hold the 1st place of this season and Mia would hold the 11th place of this season.
Edit: I forgor to mention that it also applies on the player killing and baddy killing leaderboards.
