If possible, I think it would be cool to decrease the degree of randomization for the Tyrant and Fafnir boxes in Reboot. I'm not saying to take out the randomization altogether, but just make it so that, for example, you are Thief so you only receive Lycaon Tyrants or Thief class Fafnirs. In the regular servers you can at least sell Fafnirs and Tyrants that aren't for your class, but in Reboot, you'll just be staring at $40 worth of random rewards that you can't do anything with. It just seems like Reboot players would be setting themselves up for a lot of disappointment for the Big Spender Event rewards if they're randomized to this degree. We already experience this disappointment quite often in Union Voyages when we pick up the weapon for our main class on one of our mules. x'D
Editted: People brought up good points that Tyrants and Fafnirs violate the concept of non-pay2win. Maybe some other prize for reboot servers would be cool, like perm/longer hyper tele rocks or cash boxes.
