No, seriously. This happens. I'm not happy with this event, either. But an event is an event. Chaotics work best for 11+ and for you I guess tallaars, temples and plateau. Sometimes you don't get what you want, you gotta deal with it and move on. Wait for the next weekend.
By the way can we please, please get the midweek 1v1 arena event back, admin, frank whoever is reading? (I think it was called Magic Storm on Arena)
