Same here B+. We don't need a letter or mineral to represent us. I've been told I play like an S or U during offline sessions. Reassurance right there.
Because after that half hour you get to play 20 times in a row. In ranked, you wait 30 minutes, fight one dude, then wait 30 more minutes. Best method is 3-4 man lobbies, though.
@Heikou: Beat one person with a platinum streak and you get to jump two post-S grades.
@Brute 2-5 is my limit. Hate waiting like a bread line for a match, then I'm dumb confused when it's my turn. Rank means nothing, never did. It's how you feel about your skill.
