Why it needs a rework. Make them all the same time and challenge investment of the player that plays it. Crystal Tower,as said, is to ez next to others in the same roulette. If they can rework some old stuff this should also be an option. They brought back the frontlines with its roulette and rules. I never said make it hard. Just add in more of it. The higher item level took away the experience. Why cant they work on this roulette too?
