Exactly. And the Medal event is a weekly event along with the Friend Rankings thing. You'd make far more XP (even without Double XP) doing just a few runs daily compared to buying 9,000 XP after one week. That's why I said it's a real bad trade off.

I'm just going to collect Medals for the Treasure Cabient tickets. It seems to be pretty much the only worthile investment so far from what I've seen for the last few days (the Medal Exchange market changes every 24 hours).
