It actually doesn't improve matchmaking no matter what the devs say. SP dropping is so prevalent because one, it's allowed, and two, matchmaking is so completely broken, players are kind of pushed to do it to complete events, score significantly in tournament, or simply just to win a battle.

Mind boggling how you can work for a company that outright lies to their player base while using you as their mouthpiece to do it...
