The System right know is rly fucked up, if you are not level 480+ right now you will never have enought kobones (without spending 50+€) for the event. Rebalance the Tower of Fame, set a level cap in the divisions so everyone can get 1st place. Right now if you are not hight level you must play tower of fame one week yes and one no for got a chance to get 1-4 place and loseing a week of experience. With the experience in the tower of fame hight level will be always in the top and no one will reach them.
And i'm talking only about mythic days because if i look others events too we are over 500€ for month to get every girl released
