When people say "dungeons give increased drop rate" do they mean instanced areas like the general tao mine, or areas like the red pants castle? and which ones are best for lv.50?
Also I like strategy #1. I got my last 3 today in under an hour. But I recommend finding a spot with a lot of mobs in one small are (away from roads so wandering people are less likely to take ur dbs) so u can see all the mobs on ur map. Next thing is to make sure you fight mobs with at least yellow names above their heads (red and orange names are better but harder to kill in most cases). Even if they are a lvl below u ( I got these 3 today all from mobs one lvl below me). And last, to maximize your time, make sure the mobs have low enough lp that you can kill them pretty fast with only taking little to no damage. Im lvl53 fighting lvl 52 mobs with around 4600lp. With this strategy i don't see why you can't be guaranteed at least one ball a day. I've been on 4 hunts and got all 7 of mine. And today was the first time I really used this strategy and I got 3. Good luck guys...
