I should write up a new guide to help players decide if an event is rigged. Just ask yourself a few questions:
1.) Can Oasis make money off the event? if yes, then it is rigged.
2.) Does the event in question award ninjas or materials that Oasis would rather you buy with ingots? If yes, then it is rigged.
pretty short guide, wonder if I could get it linked in the Best Strategy section of the Hot Topics tab in game...
