Think I figured out how Retainer Ventures work(the Quick ones and possibly more).

I'm really thinking it may have something to do with gear. Both of my retainers are about to be level 40, I have a PUG and ACN. The ACN has better gear or I should say gear that is appropriate for her class, The PUG I just throw whatever on like crafting/gathering/DoM/DoW gear aside from the weapon. Anyways the ACN always brings back the better items (not saying 100% always the best), But my PUG has maybe brought back like 2 very good items. My ACN has brought me a Mog king book, Garuda weapon, Deluxe manor fire place, HQ crafting gear/rings and a lot of housing stuff. So today I decided to gear my PUG in appropriate stat gear. I do get a lot of crap like crayfish, fish, tier 1 materia and other stuff.

I've never really geared both characters (other than weaponry every 5-10 levels), yet one seems to do a little better than the other. One kindly looted me a Stuffed Chocobo from someone's house earlier today and weaver gloves previously, while the other who usually finds worse gear has found HQ Fisher boots and Lv 50 PvP Gear.

It depends, did you get the ventures you paid them from fishing leves?

I would like to think that good gear has some effect on which pool you are rolling in, but its SE so its probably all one giant RNG mish mash.

Yeah, this RNG seems a little unusual as RNG systems go. I've played Borderlands and Monster Hunter and the RNG there was always rolling for very low drop items, but it still had a chance of dropping. This one seems off for some reason, can't put forth any guess to why besides what I've already said.

The RNG in this game is built off of an extremely basic algorithm, which quite frankly, isn't very good as far of random numbers go.

The long and short of it is that computers don't really do random, because they calculate everything exactly based on rigid rules - if you ask the same question a hundred times, you'll get the same answer a hundred times. Because of this, they have to be told how to approximate randomness - usually this is done by creating a software algorithm based off a seeded number. While the computer calculates this exactly, the programming ensures that it is enough to appear random. It's possible to observe this in action and predict the outcome of the next roll, but a good algorithm will ensure many thousands of rolls in each pattern.

The RNG sequence in this game is... pretty bad. I see it all the time with mining for example. Its gotten to the point now where if I start on two HQ hits, I know what point in the sequence I am at, and that the 4th hit will be HQ too. We're not talking about a few thousand attempts per repetition here, more like a few dozen. The RNG algorithm is too basic, and not very approximate to random at all.

I suppose it's ok for things like mining, where there are usually only about four potential outcomes. The problem lies when you increase the number of outcomes. The less random the system is, the less inclusive of certain outcomes it becomes.
