IS RNG GOOD OR BAD?

Well in Ragnarok Online for example those really rare items are usually very overpowered. Like one boss 0.01% drop makes you immune to magic. Now PVP in Ragnarok Online if mostly guild vs guild. If only one player of one guild has the item, they have an advantage, but other guilds will know it if they face that guild and can prepare for it and position physical attackers to hunt down the person with the item.
If that item existed more than 2-3 times, magic will become useless and the whole concept would break and make PVP boring.

Not saying it's a good concept, some server even opted to remove that item completely. But in the end it's a concept that sells well.

That seems like an example of very, very bad RNG. That's essentially a game-breaking drop, primarily if done in single-player PVP. The existence of that item alone would be enough for me to avoid (I'm assuming it's a late-game item) high-level PVP, depending on how magically-oriented I was. I understand that game developers of multiplayer games don't take emotions into account, but imagine how many magic users quit the game once the existence of that item became common knowledge; not because they had personally been robbed of victory by it, but because they might one day have to face somebody who is using it. It's an example of how one item alone can influence the class or weapon choices of thousands of people. I mean, it's so rare that you won't see it often and won't matter too much, but the fact that there could be one guy who keeps doing PVP against magic users and has that item just seems wrong to me.

When it comes to RNG-based rare drops in competitive MMOs, I feel like premium items or customization items (hair dye, premium clothing, etc.) is a better reward, because you can still brag about it or show off, but you aren't breaking the game for the poor guy who can't even hit you with the ultimate spell.
