No one's gonna share his/hers fav "hot-spot" for DBs, as they don't want to argue and swear later and see his fav place swarmed by other players.
You can also buy DBs at price of 6m per ball, in some cases even for 5m, whole wishes for 20-30m, not more.
I used to buy wishes for 20m, but last 2 wishes I hunt alone since I did a reset on my build.
Sometimes I get none, sometimes I get 3-4 balls per hunt, despite the fact I am lvl 60. No sandboxie, no little lemmings (nor big ones) helping me around. =P
Anyone want to spill out a couple good methods? I dragon ball hunt every night of my weekends and find nothing at all. I kill every single spot I could find, and still... nothing. And I don't want to dual client cause I heard that you can get ip banned for doing that in game.
