Game's RNG seems whack

I dont understand why some people do not understand that random is random.

We understand, it's just that the game does weird things from time to time.
For example, I crafted for about 6 hours yesterday (3 in the morning, 3 before bed), out of the hundreds of synths a lot ended between 80% and 89% to HQ, but only like 2 of them actually HQ'd (that were in the 80s range). I even had synths with 17% or 30% HQ, but if it was around 80% most of the time it just failed. Tell me that isn't weird.

Read my post. They already admitted one random number generator wasn't functioning properly. They all use the same system. Is it much of a stretch that some of the others might not be?

I so wish people would stop saying that, random is not random.
There are true RNG, but they are usually slow and are primarily used for cryptography, where unpredictability is more important than distribution.
Games use a pseudo RNG, where the number sequences are not really random, but rather provide good distribution of generated numbers. As long as the player can't predict the sequence this is sufficient. The sequences generated by FFXIV are not evenly distributed. SE is doing something very weird here, but as long as SE isn't providing any specific information, we can only speculate.
There's one thing is for certain though, these numbers are not random.
