if you dont know something for sure dont give people wrong advices.Drop rare doesnt decrease if you are in party,in fact it increases.

The mobs that will give you DBs are the ones that are yellow to you,that means max 3 lvls difference.Mob who is +- 5 lvls different might drop,but the rate is very low.The best thing to do is kill yellow mobs(preferably supers).

About droping in general,sometimes you will get 7 DBs in 2 hours,sometimes you wont get any for a long time.Just because you managed to collect 9 DBs during 1 weekend like i did,doesnt mean that you will get them again that easily.Its all random.Sometimes lady luck will favour you,while sometimes you will RAGE because of DBs not droping.

Those are the most important things you need to know about DBs.

Those are just things I've read on the forum, plus every time I'm in a party I can't get ****. Maybe my luck just sucks lol

there are many things that you need to learn.But you will get it in time.We all did :D
EDIT: i mean tips and tricks :D

Well, until anyone provides information VIA a quote/official statement about dragon ball drop rates, from Korean Devs, I wouldn't believe anything anyone says as it is pure speculation/hearsay. The only one that seemingly is correct is killing mobs within a certain level range to get the drop. "Seemingly" Higher ranked monsters (Supers/Ultra's/Bosses), provide better drop rates, but I've had just as much luck killing normal mobs as I have, killing higher ranked mobs, or even lower level mobs (Within a 5 level range) and gotten drops.

Again, I believe it all simply comes down to luck.

One thing i know for sure.Supers drop more then regular mobs.But ofc there are people with crazy luck who can get many DBs even on normal mobs.Still i prefer supers,especially the ones in front of Dr gero dungeon.Thats what i call a golden mine for DBs.

I couldn't get the ball to drop on a Super no matter how hard I tried. I camped out a Super box that was next to a Super mob for 6 hours and didn't get ****. But then I tried normal mobs and the Dragonballs started dropping like crazy.

I would recommend that you kill mobs of your same lvl. That's the higher drop rate you will get. And I seriously think that supers have just a slight higher drop rate than normal mobs.

If you keep killing normal mobs of your same lvl you should get a couple of easy dragonballs.

kill db mobs within 3 or 5 levels of yourself and supers/ultras/boss etc have a higher drop rate than normal mobs.

with the same level as you is the highest possible chance to get, Again as I 've said before.

At lv 53 killing lv 53 supers one can get 21 to 28 dragonballs in one weekend.

If you're referring to the dungeon I think you are, I heard that got nerfed at least a month and a half back, but it was, or perhaps still is 'The' place to farm dragon balls, again I was fairly sure I heard this place got nerfed in terms of DB farming, but generally any place with a lot of mobs you can pull+ if you can score a spin to win majin, you're set.
