I am having problems with the dragon ball hunt. I was able to get 1 to 6 star dragon balls within 1 hour of a single db hunt. and as for the final 7 star ball i have played 3 full sessions of db hunt and have not received the dragon ball yet. I am lvl 34 now fighting lvl 28-29 mobs. Need help please any one know how to solve this problem. i've been stuck for about a week trying to get the final required dragon ball with no success.
