Dang, that sucks, 2 of those are lower than SR, not even sure if it's worth it.
Also keep forgetting to ask, what's the point of the defense party? Or is it basically just set 1 and set 2? At first I thought defense party was what other players would fight in rank matches but after finding out you can check battle history of others battling you, it seems they don't fight the defense party. So what purpose does it serve?
