On a good day, i average about...500k per DAY. And that's when i stay up all night(10pm-2am.). My plans are to make at least 400k a day for six days then im buying me a whip. :D Is it really bad to get a whip in a week? I am lvl 80.
Actually, a Castle Wars world wouldn't be such a good idea, what with all the people trying to get in the game. They should make it like Pest Control, where tons of people can play at once.
