Overmelding is not fun

[Datachanger]

These points keep getting brought up.

As a savage raid leader, I, personally, told my team that you don't need to overmeld. Just do your 2 melds, and we'll be fine. And I am fully aware of my 200+ crystals built up from hunt trains.
I know spiritbonding for Gatherer materia is the way to go. Let's say I farm up 300 of each materia. But what happens when you need significantly more of one materia? You now have burnt through 300 of one materia with 200+ of the rest just sitting there. You can't target-farm Gatherer materia, this way.
Crafter materia IS annoying. Even the mid-tier melds, which is about as low as you can go to macro-craft the food/pots, is still a penta-meld. Going less is effectively trading one form of RNG for another (matiera RNG for HQ RNG).

But these points and my responses to them are ...more or less... irrelevant. Please stop bringing them up as they aren't addressing the fundamental flaw that this person brings up:

Randomness in bulk systems with low percentages has always been an issue in many systems, because randomness is not a reliable method for a balanced distribution (some players will be very lucky, some very unlucky).

I can understand talking about a system in the context of other systems, but is it so hard to criticize a system without someone saying, "But you don't have to do it"? Yeah, there are ways to try and mitigate the issue, which many of you have brought up. Regardless, seeing your hard work blown up in smoke with nothing to show for it feels bad as a player. And that is worth mentioning.

P.S.

Instead of making it scale linearly, why not require a set number of materia for a guaranteed meld?

I've thought about this, too. And I'd happily take such a system. I felt that this solution, while good, doesn't quite keep the spirit of the overmeld system as an RNG-based system. But honestly, if there is going to be an improvement to the system, this is likely to be the implemented solution. As it is probably the simplest to implement from a development perspective. But if someone can think up other deterministic solutions, as well, I would definitely be interested in discussing them!
