And that 120 Sta cost seriously... most of player can only try twice (3 times with lucky Gathers) before running out Sta...
120 Sta = 6 hours of Recovery! During all that time you don't play at all. Is that really a good idea to create Event where you play less than usual? Or that's just another mean to push players to buy and use FG?
And that's only the first part of the Event, the second will certainly cost even more.

For now I played the ?-4 maps 3 times and got only 1 Item. Fortunately it worked.
